Stability of the Leibniz additive-quadratic functional equation in quasi-beta normed space: direct and fixed point methods (English)
0 references
This work investigates a Leibniz-type functional equation. The motivation of this equation comes from Euclidean geometry.NEWLINENEWLINEThe odd and even solutions are given in the second section. The third one is about quasi-beta normed spaces, and the last two sections contain stability results.
