Abstract

In this paper we consider equilibrium problems in vector metric spaces where the function f and the set K are perturbed by the parameters @e,@h. We study the stability of the solutions, providing some results in the peculiar framework of generalized monotone functions, first in the particular case where K is fixed, then under both data perturbation.
