Trends in commutative algebra

- 1 commentaire

PREFACE :

In 2002, an introductory workshop was held at the Mathematical Sciences Research Institute in Berkeley to survey some of the many directions of the commutative algebra field. Six principal speakers each gave three lectures, accompanied by a help session, describing the interaction of commutative algebra with other areas of mathematics for a broad audience of graduate students and researchers. This book is based on those lectures, together with papers from contributing researchers. David Benson and Srikanth Iyengar present an introduction to the uses and concepts of commutative algebra in the cohomology of groups. Mark Haiman considers the commutative algebra of n points in the plane. Ezra Miller presents an introduction to the Hilbert scheme of points to complement Professor Haiman's paper. Further contributors include David Eisenbud and Jessica Sidman; Melvin Hochster; Graham Leuschke; Rob Lazarsfeld and Manuel Blickle; Bernard Teissier; and Ana Bravo.

Convexity

- Aucun commentaire

PREFACE :

Convexity provides a wide-ranging introduction for final year undergraduates and graduate students. Convex sets and functions are studied in the Euclidean space IRn, thus allowing an exposition demanding only an elementary knowledge of analysis and linear algebra, and enabling concepts to bemotivated through simple geometric examples. The fundemental ideas of convexity are natural and appealing, and does not have to travel far along its path, before meeting significant, aesthetically pleasing results. It develops geometric intuition, and is a showcase for displaying interconnections amongst different parts of mathematics, inaddition to have ties with economics, science and engineering. Despite being an active research field, it abounds in unsolved problems having an instant intuitive appeal. One distinctive feature of the book is the diverse applications that it highlights: number theory, geometric extremum problems, combinatorial geometry, linear programming, game theory, polytopes, bodies of constant width, the gamma function, minimax approximation, and linear, classical and matrixinequalities. Several topics make their first appearance in a general introduction to convexity, while a few have not appeared outside research journals. The account has a self-contained treatment of volume, thus permitting a rigorous discussion of mixed volumes, is operimetry and Brunn-Minkowskitheory. Full solutions to most of the 241 exercises are provided and detailed suggestions for further reading are given.

The Square Root of 2: A Dialogue Concerning a Number and a Sequence

- Aucun commentaire

PREFACE :

The square root of 2 is a fascinating number – if a little less famous than such mathematical stars as pi, the number e, the golden ratio, or the square root of –1. (Each of these has been honored by at least one recent book.) Here, in an imaginary dialogue between teacher and student, readers will learn why v2 is an important number in its own right, and how, in puzzling out its special qualities, mathematicians gained insights into the illusive nature of irrational numbers. Using no more than basic high school algebra and geometry, David Flannery manages to convey not just why v2 is fascinating and significant, but how the whole enterprise of mathematical thinking can be played out in a dialogue that is imaginative, intriguing, and engaging. Original and informative, The Square Root of 2 is a one-of-a-kind introduction to the pleasure and playful beauty of mathematical thinking.

Evolution algebras and their applications

- Aucun commentaire

PREFACE :

Behind genetics and Markov chains, there is an intrinsic algebraic structure. It is defined as a type of new algebra: as evolution algebra. This concept lies between algebras and dynamical systems. Algebraically, evolution algebras are non-associative Banach algebras; dynamically, they represent discrete dynamical systems. Evolution algebras have many connections with other mathematical fields including graph theory, group theory, stochastic processes, dynamical systems, knot theory, 3-manifolds, and the study of the Ihara-Selberg zeta function. In this volume the foundation of evolution algebra theory and applications in non-Mendelian genetics and Markov chains is developed, with pointers to  some further research topics.

Advanced Euclidean Geometry

- Aucun commentaire

PREFACE :

For many years, this elementary treatise on advanced Euclidean geometry has been the standard textbook in this area of classical mathematics; no other book has covered the subject quite as well. It explores the geometry of the triangle and the circle, concentrating on extensions of Euclidean theory, and examining in detail many relatively recent theorems. Several hundred theorems and corollaries are formulated and proved completely; numerous others remain unproved, to be used by students as exercises. The author makes liberal use of circular inversion, the theory of pole and polar, and many other modern and powerful geometrical tools throughout the book.

In particular, the method of "directed angles" offers not only a powerful method of proof but also furnishes the shortest and most elegant form of statement for several common theorems. This accessible text requires no more extensive preparation than high school geometry and trigonometry.

Transform methods for solving partial differential equations

- Aucun commentaire

PREFACE :

Transform methods provide a bridge between the commonly used method of separation of variables and numerical techniques for solving linear partial differential equations. While in some ways similar to separation of variables, transform methods can be effective for a wider class of problems. Even when the inverse of the transform cannot be found analytically, numeric and asymptotic techniques now exist for their inversion, and because the problem retains some of its analytic aspect, one can gain greater physical insight than typically obtained from a purely numerical approach.

Transform Methods for Solving Partial Differential Equations, Second Edition illustrates the use of Laplace, Fourier, and Hankel transforms to solve partial differential equations encountered in science and engineering. The author has expanded the second edition to provide a broader perspective on the applicability and use of transform methods and incorporated a number of significant refinements:

New in the Second Edition:
  Expanded scope that includes numerical methods and asymptotic techniques for inverting particularly complicated transforms

· Discussions throughout the book that compare and contrast transform methods with separation of variables, asymptotic methods, and numerical techniques

· Many added examples and exercises taken from a wide variety of scientific and engineering sources

· Nearly 300 illustrations--many added to the problem sections to help readers visualize the physical problems

  A revised format that makes the book easier to use as a reference: problems are classified according to type of region, type of coordinate system, and type of partial differential equation

·Updated references, now arranged by subject instead of listed all together

As reflected by the book's organization, content, and many examples, the author's focus remains firmly on applications. While the subject matter is classical, this book gives it a fresh, modern treatment that is exceptionally practical, eminently readable, and especially valuable to anyone solving problems in engineering and the applied sciences.

The book of numbers

- Aucun commentaire

PREFACE :

In THE BOOK OF NUMBERS, two famous mathematicians fascinated by beautiful and intriguing number patterns share their insights and discoveries with each other and with readers. John Conway is the showman, master of mathematical games and flamboyant presentations; Richard Guy is the encyclopedist, always on top of problems waiting to be solved. Together they show us why patterns and properties of numbers have captivated mathematicians and non-mathematicians alike for centuries. THE BOOK OF NUMBERS features Conway and Guy's favorite stories about all the kinds of numbers any of us is likely to encounter, and many others besides. "Our aim," the authors write, "is to bring to the inquisitive reader. . .an explanation of the many ways the word 'number' is used." They explore patterns that emerge in arithmetic, algebra, and geometry, describe these pattern' relevance both inside and outside mathematics, and introduce the strange worlds of complex, transcendental, and surreal numbers. This unique book brings together facts, pictures and stories about numbers in a way that no one but an extraordinarily talented pair of mathematician/writers could do.

The Foundations of Mathematics

- Aucun commentaire

PREFACE :

The transition from school mathematics to university mathematics is seldom straightforward. 

Students are faced with a disconnect between the algorithmic and informal attitude to mathematics at school, versus a new emphasis on proof, based on logic, and a more abstract development of general concepts, based on set theory.

The authors have many years' experience of the potential difficulties involved, through teaching first-year undergraduates and researching the ways in which students and mathematicians think. The book explains the motivation behind abstract foundational material based on students' experiences of school mathematics, and explicitly suggests ways students can make sense of formal ideas.

This second edition takes a significant step forward by not only making the transition from intuitive to formal methods, but also by reversing the process- using structure theorems to prove that formal systems have visual and symbolic interpretations that enhance mathematical thinking. This is exemplified by a new chapter on the theory of groups.

While the first edition extended counting to infinite cardinal numbers, the second also extends the real numbers rigorously to larger ordered fields. This links intuitive ideas in calculus to the formal epsilon-delta methods of analysis. The approach here is not the conventional one of 'nonstandard analysis', but a simpler, graphically based treatment which makes the notion of an infinitesimal natural and straightforward. This allows a further vision of the wider world of mathematical thinking in which formal definitions and proof lead to amazing new ways of defining, proving, visualising and symbolising mathematics beyond previous expectations.

Problems and Theorems in Analysis : Series · Integral Calculus · Theory of Functions

- Aucun commentaire

PREFACE :

The present English edition is not a mere translation of the German original. Many new problems have been added and there are also other changes, mostly minor. Yet all the alterations amount to less than ten percent of the text. We intended to keep intact the general plan and the original flavor of the work. Thus we have not introduced any essentially new subject matter, although the mathematical fashion has greatly changed since 1924. We have restricted ourselves to supplementing the topics originally chosen. Some of our problems first published in this work have given rise to extensive research. To include all such developments would have changed the character of the work, and even an incomplete account, which would be unsatisfactory in itself, would have cost too much labor and taken up too much space. We have to thank many readers who, since the publication of this work almost fifty years ago, communicated to us various remarks on it, some of which have been incorporated into this edition. We have not listed their names; we have forgotten the origin of some contributions, and an incomplete list would have been even less desirable than no list. The first volume has been translated by Mrs. Dorothee Aeppli, the second volume by Professor Claude Billigheimer. We wish to express our warmest thanks to both for the unselfish devotion and scrupulous conscientiousness with which they attacked their far from easy task.

Statistique et probabilités en économie-gestion

- Aucun commentaire

AVANT-PROPOS :

Qu'est-ce que la statistique? La statistique est une science recouvrant plusieurs dimensions. On emploie d'ailleurs très fréquemment le pluriel «statistiques» pour désigner cette discipline et témoigner ainsi de sa diversité. La statistique englobe la recherche et la collecte de données, leur traitement et leur analyse, leur interprétation, leur présentation sous la forme de tableaux et graphiques, .le calcul d' indicateurs permettant de les caractériser et synthétiser ... Ces différents éléments renvoient à ce que l'on a coutume de nommer la statistique descriptive, fondée sur l'observation de données relatives à toutes sortes de phénomènes (économiques, financiers, historiques, géographiques, biologiques, etc.).
Il arrive cependant fréquemment que les données représentatives du phénomène que l'on souhaite étudier ne so ient pas parfaitement connues, c'est-à-dire pas toutes parfaitement observables, au sens où elles ne fournissent qu' une information partielle sur !'ensemble du phénomène que l'on analyse. Afin de pouvoir en réaliser une étude statistique, il est alors nécessaire d' inférer des informations à partir des quelques éléments dont on dispose. En d' autres termes, le statisticien devra effectuer des hypothèses concernant les lois de probabilité auxquelles obéit le phénomène à analyser. La statistique fait alors appel à la théorie des probabi lités et est qualifiée de stati stique mathématique ou encore de statistique inférentielle.
Un bref retour sur l'histoire. Même si le terme de «stati stique» est généralement considéré comme datant du xvme siècle1 , le recours à cette discipline remonte à un passé bien plus éloigné. On fait en effet souvent référence à la collecte de données en Chine en 2238 av. J. -C. concernant les productions agricoles, ou encore en Égypte en 1700 av. J.-C. en référence au cadastre et au cens. La collecte de données à des fins descriptives est ainsi bien ancienne, mais ce n'est qu'au xvme siècle qu'est apparue l'idée d' utiliser les statistiques à des fins prévisionnelles. Ce fut le cas en démographie où les statistiques collectées lors des recensements de la population ont permis l'élaboration de tables de mortalité en Suède et en France.
Du côté des mathématiciens, les recherches sur le calcul des probabilités se sont développées dès le XVIIe siècle, au travers notamment des travaux de Fermat et Pascal. Même si Condorcet et Laplace ont proposé quelques exemples d'application de la théorie des probabilités, ce n'est qu ' au cours de la deuxième moitié du XIXe siècle, grâce aux travaux de Quételet, que l' apport du calcul des probabilités à la statistique fut réellement mis en évidence, conduisant ainsi aux prémisses de la statistique mathématique. Cette dernière s' est ensuite largement développée à la fin du XIXe siècle et dans la première moitié du XXe siècle.
Par la suite, grâce notamment aux progrès de l' informatique peu avant la deuxième moitié du XXe siècle, de nouvelles méthodes d'analyse ont vu le jour, comme l'analyse multidimensionnelle permettant d'étudier de façon simultanée plusieurs types de données. La deuxième moitié du xxe siècle est aussi la période durant laquelle plusieurs courants de pensée en statistiques' affrontent, notamment autour de la notion de probabilité .
Les domaines d' application de la statistique sont multjples. Initialement employée en démographie, elle est en effet utilisée dans toutes les sciences humaines et sociales comme l'économje, la finance, la gestion, le marketing, l'assurance, l'histoire, la sociologie, la psychologie, etc., mais aussi en médecine, en sciences de la terre et du vivant (biologie, géologie ... ), météorologie, etc. Cet éventail des domaines illustre ainsi toute la richesse de la statistique dont cet ouvrage vise à rendre compte.

Comment synthétiser et interpréter l’information contenue dans des données économiques et financières ? Comment analyser et quantifier la relation entre plusieurs séries ? Qu’est-ce qu’une loi de probabilité ? Comment estimer un modèle et mettre en oeuvre des tests statistiques ?
Alliant théorie et pratique, ce manuel met l’accent sur l’acquisition des méthodes et des compétences indispensables à tout étudiant pour réussir sa licence ou
son bachelor. Il propose :
  • des situations concrètes pour introduire les concepts ;
  • un cours visuel et illustré par de nombreux exemples pour acquérir les connaissances fondamentales en statistique et probabilités ;
  • des conseils méthodologiques et des interviews pour traduire la théorie en pratique et montrer comment la statistique est utilisée par les professionnels ;
  • des éclairages sur les grands auteurs de la discipline ;
  • des exercices progressifs et variés (QCM, problèmes, sujets d’examen) pour s’évaluer et s’entraîner.
