1. Fixed point method for set-valued functional equations.

Author

Park, Choonkil

Abstract

In this paper, we introduce a set-valued cubic functional equation and a set-valued quartic functional equation and prove the Hyers-Ulam stability of the set-valued cubic functional equation and the set-valued quartic functional equation by using the fixed point method. [ABSTRACT FROM AUTHOR]
