Generalized Ulam-Hyers Stability of a General Mixed AQCQ-functional Equation in Multi-Banach Spaces: a Fixed Point Approach

Tian Zhou Xu, John Michael Rassias, Wan Xin Xu


Using the fixed point method, we investigate the generalized Hyers-Ulam stability of the general mixed additive-quadratic-cubic-quartic functional equation

in multi-Banach spaces.
