TY - JOUR AU - Bodaghi, Abasalt AU - Fošner, Ajda PY - 2021 DA - 2021/03/10 TI - Characterization, stability and hyperstability of multi-quadratic–cubic mappings JO - Journal of Inequalities and Applications SP - 49 VL - 2021 IS - 1 AB - In this paper, we unify the system of functional equations defining a multi-quadratic–cubic mapping to a single equation. Applying a fixed point theorem, we study the generalized Hyers–Ulam stability of multi-quadratic–cubic mappings. As a result, we investigate the hyperstability of multi-quadratic–cubic mappings in some senses.
