Fuzzy Stability of an n -Dimensional Quadratic and Additive Functional Equation

摘要

We will investigate a fuzzy version of stability for the functional equation 2f(Σ_ from i=1 to n of (x_i)) + Σ_(1≤i,j≤n,i,i≠j) f (x_i-x_j) = (n + 1) Σ_ from i=1 to n of f(x_i) + (n - 1) Σ_ from i=1 to n f(-(x_i)) in the sense of Mirmostafaee and Moslehian.%150815
