Introductionear theory required in the process. This means we shall be concerned with the solvability of boundary value problems (primarily the Dirichlet problem) and related general properties of solutions of linear equations.and of quasilinear equations.Here . = (..., … , ...), where ... = ∂./∂.., ...= ∂../∂.

Banach and Hilbert Spaces 8. This material will be familiar to a reader already versed in basic functional analysis but we shall assume some acquaintance with elementary linear algebra and the theory of metric spaces. Unless otherwise indicated, all linear spaces used in this book are assumed to be defined over the real num

Classical Solutions; the Schauder Approachamental observation that equations with Hölder continuous coefficients can be treated locally as a perturbation of constant coefficient equations. From this fact Schauder was able to construct a global theory, an extension of which is presented here. Basic to this approach are apriori esti

Topological Fixed Point Theorems and Their Applicationtes for solutions. This reduction is achieved through the application of topological fixed point theorems in appropriate function spaces. We shall first formulate a general criterion for solvability and illustrate its application in a situation where the required apriori estimates are readily derive
