Abstract
Given a sequence of functions converging in some topology to a function , in general the 0-level set of does not give a good approximation of the one of . In this paper we show that, if we consider an appropriate perturbation of the 0-level set of , we get a sequence of sets converging to the 0-level set of , where the type of set convergence depends on the type of convergence of to .
