Sobolev
spaces are a fundamental tool in the modern study of
partial differential equations. In this book,
Leoni
takes a novel
approach to the theory by looking at Sobolev spaces as the
natural development of monotone, absolutely continuous, and
BV functions of one variable. In this way, the majority of the text
can be read without the prerequisite of a course in functional
analysis.
The first part of this text is devoted to studying functions of one
variable. Several of the topics treated occur in courses on real analysis or measure
theory. Here, the perspective emphasizes their applications to Sobolev functions,
giving a very different flavor to the treatment This elementary start to the book
makes it suitable for advanced undergraduates or beginning graduate students.
Moreover, the one-variable part of the book helps to develop a solid background
that facilitates the reading and understanding of Sobolev functions of several vari¬
ables.
The second part of the book is more classical, although it also contains some recent
results. Besides the standard results on Sobolev functions, this part of the book
includes chapters on BV functions, symmetric rearrangement, and
Besov
spaces.
The book contains over
200
exercises.
