Abstract

Abstract This article is a survey on boundedness results for stable solutions to semilinear elliptic problems. For these solutions, we present the currently known L ${L^{\infty}}$ estimates that hold for all nonlinearities. Such estimates are known to hold up to dimension 4. They are expected to be true also in dimensions 5 to 9, but this is still an open problem which has only been established in the radial case.
