 Title HYERS-ULAM-RASSIAS STABILITY OF A QUADRATIC-ADDITIVE TYPE FUNCTIONAL EQUATION IN FUZZY SPACES Publication Type Journal Article Year of Publication 2015 Authors Sun-Sook, J, Lee, Y-H Journal International Electronic Journal of Pure and Applied Mathematics Volume 9 Issue 3 Start Page 121 Pagination 16 Date Published 05/2015 Type of Article Scientific article ISSN 1314-0744 Keywords fuzzy almost quadratic-additive mapping, fuzzy normed space, quadratic-additive type functional equation Abstract In this paper, we investigate a fuzzy version of stability for the functional equation $$f((a-1)x+y)+(a-1)f(x-y)+f(ax)-(a^2+a-1)f(x) \\ -(a-1)^2f(-x)- f(y)-(a-1)f(-y)=0$$ in the sense of A.
