Functional Analysis, Sobolev Spaces and Partial Differential Equations: Universitext

Autor Haim Brezis
en Limba Engleză Paperback – 10 noi 2010

Ne-a atras atenția modul în care Functional Analysis, Sobolev Spaces and Partial Differential Equations reușește să sintetizeze interdisciplinaritatea dintre analiza funcțională abstractă și aplicațiile sale directe în studiul ecuațiilor cu derivate parțiale. Această ediție din 2011, publicată de Springer în seria Universitext, nu este doar o traducere a celebrului text francez din 1983, ci o expansiune considerabilă care adaptează rigoarea matematică la nevoile cercetării contemporane. Considerăm că forța acestui volum rezidă în capacitatea de a prezenta spațiile Sobolev nu ca pe un subiect izolat, ci ca pe un instrument indispensabil pentru formularea variațională a problemelor la limită. Structura cursului este una progresivă: primele șase capitole pun bazele operatorilor liniari, topologiilor slabe și descompunerii spectrale, în timp ce a doua jumătate a cărții, începând cu capitolul 7 dedicat teoremei Hille-Yosida, pivotează decisiv către EDP și ecuațiile de evoluție (căldură și unde). Merită menționat că Haim Brezis își continuă aici preocuparea pentru structurile matematice complexe, observată și în Nonlinear Evolution Equations and Related Topics, însă într-un format pedagogic mult mai accesibil studenților. Comparativ cu Functional Spaces for the Theory of Elliptic Partial Differential Equations de Françoise Demengel, care se concentrează strict pe regularitatea soluțiilor în probleme eliptice, lucrarea lui Brezis oferă o perspectivă mai largă, integrând analiza funcțională generală ca un fundament unitar. De asemenea, spre deosebire de Functional Analysis for the Applied Sciences de Gheorghe Moroșanu, care pune accent pe aplicații în științe aplicate, textul de față rămâne ancorat într-o rigoare teoretică pură, fiind esențial pentru cei care doresc să înțeleagă mecanismele intime ale analizei moderne.

Recenzii

From the reviews:
“Brezis has intelligently chosen several fundamental concepts of functional analysis, and has build the book around them and their applications. … for a newcomer who intends to become a user of functional analysis this book is an ideal place to start. In fact I would recommend this over any other source to any beginning graduate student. … the book also has all the basic tools for a beginer PDE researcher … . Its a bible for the field of research.” (Philosophy, Religion and Science Book Reviews, bookinspections.wordpress.com, October, 2013)
“This textbook has its origin in the French version Analyse fonctionnelle published in 1985, which has become a standard reference and was translated into several languages. … At the end of each chapter the reader will find comments with further information, references, and historic remarks. … In summary, the present textbook provides an excellent basis for a course on functional analysis plus a follow-up course on partial differential equations. It is well-written and I can wholeheartedly recommend it to both students and teachers.” (G. Teschl, Monatshefte für Mathematik, Vol. 165 (3-4), March, 2012)
“This book is a tour de force by the author, who is a master of modern nonlinear functional analysis and who has contributed extensively to the development of the theory of partial differential equations. … The writing is lively, the material is diverse and maintains a strong unity. … the book is a very useful contribution to the growing literature on this circle of ideas. I wholeheartedly recommend this book both as a textbook, as well as for independent study.” (Vicenţiu Rădulescu, Mathematical Reviews, Issue 2012 a)
“The book is the English translation of an 1983 book published in French: Analyse fonctionnelle :théorie et applications … . It has seen translations into numerous languages and the Springer edition was especially anticipated, as it announced a number of practice exercisesfollowing each chapter. I can honestly say that it was well worth the wait. … The text is a pleasure to read. … I wholeheartedly recommend this book as both a textbook as well as for independent study.” (Florin Catrina, The Mathematical Association of America, June, 2011)

Textul de pe ultima copertă

Uniquely, this book presents a coherent, concise and unified way of combining elements from two distinct “worlds,” functional analysis (FA) and partial differential equations (PDEs), and is intended for students who have a good background in real analysis. This text presents a smooth transition from FA to PDEs by analyzing in great detail the simple case of one-dimensional PDEs (i.e., ODEs), a more manageable approach for the beginner. Although there are many books on functional analysis and many on PDEs, this is the first to cover both of these closely connected topics. Moreover, the wealth of exercises and additional material presented, leads the reader to the frontier of research. This book has its roots in a celebrated course taught by the author for many years and is a completely revised, updated, and expanded English edition of the important “Analyse Fonctionnelle” (1983). Since the French book was first published, it has been translated into Spanish, Italian, Japanese, Korean,Romanian, Greek and Chinese. The English version is a welcome addition to this list. The first part of the text deals with abstract results in FA and operator theory. The second part is concerned with the study of spaces of functions (of one or more real variables) having specific differentiability properties, e.g., the celebrated Sobolev spaces, which lie at the heart of the modern theory of PDEs. The Sobolev spaces occur in a wide range of questions, both in pure and applied mathematics, appearing in linear and nonlinear PDEs which arise, for example, in differential geometry, harmonic analysis, engineering, mechanics, physics etc. and belong in the toolbox of any graduate student studying analysis.
