Description
Designed to bridge the gap between graduate-level texts in partial differential equations and the current literature in research journals, this text introduces students to a wide variety of more modern methods -- especially the use of functional analysis -- which has characterized much of the recent development of PDEs.
Features
covers the modern, functional analytic methods in use today -- especially as they pertain to nonlinear equations.
maintains mathematical rigor and generality whenever possible -- but not at the expense of clarity or concreteness.
offers a rapid pace -- with some proofs and applications relegated to exercises.
unlike other texts -- which start with the treatment of second-order equations -- begins with the method of characteristics and first-order equations, with an emphasis in itsconstructive aspects.
introduces the methods by emphasizing important applications.
illustrates topics with many figures.
contains nearly 400 exercises, most with hints or solutions.
provides chapter summaries.
lists references for further reading.
