✦ Synopsis

In this paper we consider the open complement U of a hypersurface Y = V a in an affine scheme X. We study the relations between the affineness of U, the intersection of Y with closed subschemes, the property that every closed surface in U is affine, the property that every analytic closed surface is Stein, and the superheight of a defining ideal a.

## Abstract We study the asymptotic behaviour of the solution __u__~__n__~ of a linear elliptic equation posed in a fixed domain Ξ©. The solution __u__~__n__~ is assumed to satisfy a Dirichlet boundary condition on Ξ“~__n__~, where Ξ“~__n__~ is an arbitrary sequence of subsets of βˆ‚Ξ©, and a Neumman bou
