Calculus of Variationsby I M Gelfand
Synopses & ReviewsPublisher Comments:Based on a series of lectures given by I. M. Gelfand at Moscow State University, this book actually goes considerably beyond the material presented in the lectures. The aim is to give a treatment of the elements of the calculus of variations in a form both easily understandable and sufficiently modern. Considerable attention is devoted to physical applications of variational methods, e.g., canonical equations, variational principles of mechanics, and conservation laws. The reader who merely wishes to become familiar with the most basic concepts and methods of the calculus of variations need only study the first chapter. Students wishing a more extensive treatment, however, will find the first six chapters comprise a complete universitylevel course in the subject, including the theory of fields and sufficient conditions for weak and strong extrema. Chapter 7 considers the application of variational methods to the study of systems with infinite degrees of freedom, and Chapter 8 deals with direct methods in the calculus of variations. The problems following each chapter were made specially for this Englishlanguage edition, and many of them comment further on corresponding parts of the text. Two appendices and suggestions for supplementary reading round out the text. Substantially revised and corrected by the translator, this inexpensive new edition will be welcomed by advanced undergraduate and graduate students of mathematics and physics. Synopsis:This fresh, lively text serves as a introduction to calculus variations, with applications to the mechanics of systems with a finite number of degrees of freedom. The first six chapters — comprising a university course in the subject — include the theory of fields and sufficient conditions for weak and strong extrema. Chapter 7 considers the application of variational methods to sytems with infinite degrees of freedom, and chapter 8 deals with direct methods in the calculus of variations. Problems follow each chapter and the two appendices. This inexpensive new edition, substantially revised and corrected by the translator, is easily understandable and ideal for advanced undergraduate and graduate mathematics and physics students.
