Fixed points and stability of functional equations in fuzzy ternary Banach algebras

By using Diaz and Margolis fixed point theorem, we establish the generalized Hyers-Ulam-Rassias stability of the ternary homomorphisms and ternary derivations between fuzzy ternary Banach algebras associated to the following (m,n)-Cauchy-Jensen additive functional equation: (1 <= 1<...<im <= n 1 <= kj <= n k1ij,j is an element of{1,...,m})Sigma f(Sigma(m)(j=1) x(ij)/m + Sigma(n-m)(i=1) x(kj)) = (n-m+1)/n (n m) Sigma(n)(i=1) f(X-j).
