This paper introduces a new type of generalized mixed-type quadratic-additive functional equation and obtains its general solution. The main goal of this work is to investigate Ulam stability of this mixed type of quadratic-additive functional equation in the setting of non-Archimedean fuzzy phi-2-normed space and non-Archimedean Banach space using the direct and fixed point approaches, considering two cases: even mapping and odd mapping.
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 stability of this mixed type of quadratic-additive functional equation in the setting of non-Archimedean fuzzy phi-2-normed space and non-Archimedean Banach space using the direct and fixed point approaches by taking into our account two cases: even mapping and odd mapping.
