Title: Bi-additive functional inequalities and biderivations and bihomomorphisms in C*-triple systems

Abstract:

In this talk, we use the fixed point method to investigate the Hyers-Ulam stability of C*-ternary bimultipliers and C*-ternary Jordan bimultipliers on C*-ternary algebras for
the following 2-dimensional  functional equation
 f(x+y,z+w)+f(x+y,z-w)+f(x-y,z+w)+f(x-y,z-w)=4f(x,z).
