Some Results on Stability of a General Functional Equation in m-Banach Spaces
摘要
In this paper, some remarks on the paper (Ciepliński in Bull Malays Math Sci Soc 46:62, 2023) are provided. The main results of the manuscript enhance those presented by Ciepliński. We establish the Hyers–Ulam stability and hyperstability under various conditions, addressing open problems posed by Ciepliński. Our results, provide broader and more general results compared to previous findings.
