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.

多二次立方映射的特征，稳定性和超稳定性

在本文中，我们统一了定义多个二次立方到单个方程的功能方程组。应用不动点定理，我们研究了多二次立方映射的广义Hyers-Ulam稳定性。结果，我们从某种意义上研究了多二次立方映射的超稳定性。
