Partial differential equations are
fundamental to the modeling of natural phenomena, arising in every
field of science. Consequently,the desire to understand the
solutions of these equations has always had a prominent place in
the efforts of mathematicians; it has inspired such diverse fields
as complex function theory, functional analysis and algebraic
topology. Like algebra, topology, and rational mechanics,partial
differential equations are a core area of mathematics. This book
aims to provide the background necessary to initiate work on a
Ph.D. thesis in PDEs for beginning graduate students. Prerequisites
include a truly advanced calculus course and basic complex
variables.Lebesgue integration is needed only in Chapter 10, and
the necessary tools from functional analysis are developed within
the course. The book can be used to teach a variety of different
courses. This new edition features new problems throughout and the
problems have been rearranged in each section from simplest to most
difficult. New examples have also been added. The material on
Sobolev spaces has been rearranged and expanded. A new section on
nonlinear variational problems with "Young- measure" solutions
appears. The reference section has also been expanded.

有时候看英文书也是一种享受啊
专业书籍，内行当宝，外行当草。
纸张质量稍微不如“续一”系列的，稍微白一点、脆一点60 几何VI: 黎曼几何 这一本比它还厚一点，纸张质量也好一点，价钱却便宜一点，只要96！哎
