Approximation of general Pexider functional inequalities in fuzzy Banach spaces

摘要

In this paper, we investigate a fuzzy version of a generalized Hyers-Ulam-Rassias type stability for the following Pexider functional inequalities[f(x+y)+f(x-y)+g(z)+h(l) leqkpleft(rac{2x+z+l}{k}ight) ,][ f(x+y)+f(x-y) + g(z)+k h(l) leqkpleft(rac{ x+ z }{k}+light) ,]where $k$ are nonzero real scalars. In the fuzzy normed linear space setting is presented. In this condition, we give an alternative proof of this result in fuzzy Banach space.
