The Green function has played a key role in the analytical approach that in recent years has led to important developments in the study of stochastic processes
This title offers a systematic presentation of the properties and applications of elliptic integro-differential operators. It also includes three chapters of in
In the few years since their appearance in the mid-sixties, variational inequalities have developed to such an extent and so thoroughly that they may now be con
This volume is intended as an essentially self contained exposition of portions of the theory of second order quasilinear elliptic partial differential equation
In the theory of partial differential equations, the study of elliptic equations occupies a preeminent position, both because of the importance which it assumes
