Description
Springer Elliptic Partial Differential Equations of Second Order by David Gilbarg, Neil S. Trudinger
From the reviews: "This is a book of interest to any having to work with differential equations, either as a reference or as a book to learn from. The authors have taken trouble to make the treatment self-contained. It (is) suitable required reading for a PhD student." --New Zealand Mathematical Society, 1985_x000D_ Table of contents :- _x000D_
