AbstractIn the last decades, comparison results of Talenti type for Elliptic Problems with Dirichlet boundary conditions have been widely investigated. In this paper, we generalize the results obtained in Alvino et al. (Commun Pure Appl Math, to appear) to the case of p-Laplace operator with Robin boundary conditions. The point-wise comparison, obtained in Alvino et al. (to appear) only in the planar case, holds true in any dimension if p is sufficiently small.

The purpose of this paper is to establish the expansion theorem for a regular right-definite eigenvalue problem for the Laplace operator inRn,(n≥2)with an eigenvalue parameterλcontained in the equation and the Robin boundary conditions on two “parts” of a smooth boundary of a simply connected bounded domain.
