The goal of the book is to extend classical regularity theorems for solutions of linear elliptic partial differential equations to the context of fully nonlinea

Nonlinear elliptic differential equations are a diverse subject with important applications to the physical and social sciences and engineering. They also arise

Approach your problems from the It isn't that they can't see the right end and begin with the solution. It is that they can't see answers. Then one day, perhaps

This textbook presents the essential parts of the modern theory of nonlinear partial differential equations, including the calculus of variations. After a short

This book presents applications of noncommutative and nonassociative algebras to constructing unusual (nonclassical and singular) solutions to fully nonlinear e
