maximum principles (both for weak and classical solutions), interior Sobolev regularity and boun-dary regularity of Lipschitz type. 1. Introduction The goal of this paper is to develop a systematic study of mixed operators. The word “mixed” refers here to the diﬀerential (or pseudo-diﬀerential) order of the operator, and to the type of the. This book is intended to give a serious and reasonably complete introduction to algebraic geometry, not just for (future) experts in the ﬁeld. The exposition serves a narrow set of goals (see §), and necessarily takes a particular point of view on the subject. It has now been four decades since David Mumford wrote that algebraic ge-.

In the mathematical fields of partial differential equations and geometric analysis, the maximum principle refers to a collection of results and techniques of fundamental importance in the study of elliptic and parabolic differential equations.. In the simplest case, consider a function of two variables u(x,y) such that ∂ ∂ + ∂ ∂ = The weak maximum principle, in this setting, says that.

This paper is concerned with a class of boundary value problems for fully nonlinear elliptic PDEs involving the p-Hessian operator. We first derive a maximum principle for a suitable function involving the solution u(x) and its gradient.

This maximum principle is then applied to obtain some sharp estimates for the solution and the magnitude of its gradient. We also investigate some symmetry.
