Approximation by Solutions of Elliptic Boundary Value Problems

  • Chapter
Multivariate Approximation and Interpolation

Abstract

The background of the subject of the lecture are classical results about approximation by holomorphic or harmonic functions. The special aspect here consists in the boundary conditions for the approximating functions, which are solutions of general elliptic equations in a bounded domain Ω. Among other things, approximation is studied in different function spaces on closed or non-closed surfaces within Ω, on general compact sets or on open subsets.
