Abstract

A celebrated result by Gidas, Ni & Nirenberg asserts that classical positive solutions to semilinear equations Δu=f(u)- \Delta u = f(u) in a ball vanishing at the boundary must be radial and radially decreasing. In this paper we consider small perturbations of this equation and study the quantitative stability counterpart of this result.
