- Abstract
- In this paper, we investigate the following functional inequalities f(x)+f(y)+ f(z)parallel to <= parallel to f(x+ z)parallel to (0,1) and f(x)+f(y)+ 2f(z)parallel to <= parallel to 2f(x+y)/2 + z)parallel to (0,2) in fuzzy normed vector spaces and prove the generalized Hyers-Ulam stability of the functional inequalities (0.1) and (0.2) in fuzzy normed vector spaces in the spirit of the Th.M. Rassias stability approach.
