Elliptic Partial Differential Equations of Second Order
by D Gilbarg and N S Trudinger
Published 20 December 1977
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
