"This book can be highly recommended to every reader interested in functional analysis and its applications"(MathSciNet on Sobolev Spaces, First Edition)Sobolev Spaces presents an introduction to the theory of Sobolev spaces and related spaces of function of several real variables, especially the imbedding characteristics of these spaces. This theory is widely used in Pure and Applied Mathematics and the Physical Sciences.This second edition of Adams' classic reference text contains many additions and much modernizing and refining of material. The basic premise of the book remains unchanged:Sobolev Spaces is intended to provide a solid foundation in these spaces for graduate students and researchers alike.
