Mathematics : Algebra

A text aimed at both geometers needing the tools of rational homotopy theory to understand and discover new results concerning various geometric subjects, and topologists who require greater breadth of knowledge about geometric applications of the algebra of homotopy theory. - ;Rational homotopy is a very powerful tool for differential topology and geometry. This text aims to provide graduates and researchers with the tools necessary for the use of rational homotopy in geometry. Algebraic Models in Geometry has been written for topologists who are drawn to geometrical problems amenable to topological methods and also for geometers who are faced with problems requiring topological approaches and thus need a simple and concrete introduction to rational. homotopy. This is essentially a book of applications. Geodesics, curvature, embeddings of manifolds, blow-ups, complex and K--auml--;hler manifolds, symplectic geometry, torus actions, configurations and arrangements are all covered. The chapters related to these subjects act as an introduction to the topic, a. survey, and a guide to the literature. But no matter what the particular subject is, the central theme of the book persists; namely, there is a beautiful connection between geometry and rational homotopy which both serves to solve geometric problems and spur the development of topological methods. - more...

The text of the first volume of the book covers the major topics in ring and module theory and includes both fundamental classical results and more recent developments. The basic tools of investigation are methods from the theory of modules, which allow a very simple and clear approach both to classical and new results. An unusual main feature of this book is the use of the technique of quivers for studying the structure of rings. A considerable part of the first volume of the book is devoted to a study of special classes of rings and algebras, such as serial rings, hereditary rings, semidistributive rings and tiled orders. Many results of this text until now have been available in journal articles only. This book is aimed at graduate and post-graduate students and for all mathematicians who use algebraic techniques in their work. This is a self-contained book which is intended to be a modern textbook on the structure theory of associative rings and algebras and is suitable for independent study. more...

This book deals with numerical analysis for certain classes of additive operators and related equations, including singular integral operators with conjugation, the Riemann-Hilbert problem, Mellin operators with conjugation, double layer potential equation, and the Muskhelishvili equation. The authors propose a unified approach to the analysis of the approximation methods under consideration based on special real extensions of complex C*-algebras. The list of the methods considered includes spline Galerkin, spline collocation, qualocation, and quadrature methods. more...

"La matematica ?? la regina delle scienze e l'aritmetica ?? la regina delle matematiche"; cos?? scrisse Carl Friedrich Gauss, L'insegnamento della matematica, tanto a livello universitario quanto a livello di scuola secondaria, sembra aver dimenticato l''autorevole precetto del princeps mathematicorum. Solo in anni recenti si potuto riscontrare un'inversione di tendenza. La scoperta, avvenuta nel 1977 da parte di tre ricercatori del M.I.T., che un risultato risalente a Fermat e generalizzato da Eulero poteva essere utilizzato per la costruzione di codici crittografici difficilmente decifrabili, ha destato un forte ritorno di interesse per l'aritmetica da parte di ambienti industriali, bancari e militari. Problemi antichi, come la scomposizione degli interi in fattori primi, hanno ricevuto in anni recentissimi un rinnovato interesse. Questo volumetto, scritto in una prospettiva didattica, vuole essere un contributo alla rilettura in chiave algoritmica di alcuni classici argomenti della teoria elementare dei numeri e un invito a letture pi?? impegnative, secondo le indicazioni fornite dalla bibliografia annessa ad esso. more...
