Opis:: In this paper, we obtain the general solution of a reciprocal type functional equation of the type f(x+y)=f((k_1 x+k_2 y)/k)f((k_2 x+k_1 y)/k)/(f((k_1 x+k_2 y)/k)+f((k_2 x+k_1 y)/k) ) and investigate its generalized Ulam-Hyers stability in non-Archimedean fields where k>2, k_1 and k_2 are positive integers with k=k_1+k_2 and k_1≠k_2. We also establish Hyers-Ulam-Rassias stability, Ulam-Gavruta-Rassias stability and J.M. Rassias stability controlled by the mixed product-sum of powers of norms for the same equation.

Opis:: Using fixed point methods, we prove the generalized Hyers-Ulam stability of homomorphisms in multi-Banach algebras and derivations on multi-Banach algebras for the additive functional equation \[ \sum_{i=1}^m f\left(mx_i+\sum_{j=1, j\not=i}^m x_j\right) + f\left(\sum_{i=1}^m x_i\right) = 2 f \left(\sum_{i=1}^{m} mx_i\right) \] for each \(m\in \mathbb{N}\) with \(m\geq 2\).
