摘要: In this paper, we define a new class of control functions through aggregate special functions. These class of control functions help us to stabilize and approximate a tri-additive $\boldsymbol{\psi}$-functional inequality to get a better estimation for permuting tri-homomorphisms and permuting tri-derivations in unital $C^*$-algebras and Banach algebras by the vector-valued alternative fixed point theorem.

关键词: permuting tri-homomorphism in Banach algebra, permuting tri-derivation on $C^*$-algebra, fixed point theorem, Ulam-Hyers-Rassias stability, aggregate special functions, tri-additive $\boldsymbol{\psi}$-functional inequality
