Let A, B be two ternary algebras. A mapping H: A→ B is called a ternary cubic
homomorphism if H is a cubic function, which satisfies: H ([x, y, z])=[H (x), H (y), H (z)] for all …

In this paper, we introduce and solve of the radical quadratic and radical quartic functional
equations: We also establish some stability results in 2-normed spaces and then the stability …

In this work, we introduce a new type of generalized mixed-type quadratic-additive functional
equation and obtain its general solution. The main goal of this work is to investigate Ulam …

Let A be a C∗-ternary algebra. A C-bilinear T: A× A→ A is called a C∗-ternary algebra bi-

In 1897, Hensel discovered the p-adic numbers as a number theoretical analogue of power
series in complex analysis. The most important examples of non-Archimedean spaces are p …
