Quadratic-Quartic Functional Equations in RN-Spaces

초록

We obtain the general solution and the stability result for the following functional equation in random normed spaces (in the sense of Sherstnev) under arbitrary t-norms f (2x + y) + f (2x - y) = 4 [f (x + y) + f(x-y)] + 2[f (2x) - 4f (x)] - 6f (y).
