Spazi di Sobolev con peso e problemi ellittici in un angolo. (I)

Abstract

This work, which consists of three parts, is concerned with boundary value problems for linear partial differential equations of elliptic type in a plane sector. They have been investigated within suitable Sobolev weight spaces. In this first part of the work Sobolev weight spaces are studied. Duality, embedding and trace theorems have been proved. © 1973 Nicola Zanichelli Editore.
