标题: C*-triple bimultipliers and C*-triple Jordan bimultipliers in C*-triple systems and C*-ternary algebras
摘要: 
In this talk, we use the fixed point method and the direct method to investigate the Hyers-Ulam stability of C*-triple bimultipliers and C*-triple Jordan bimultipliers on C*-triple systems and 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)=4 f(x,z). This is applied to investigate bihomomorphisms in C*-algebras, Lie C*-algebras and JC*-algebras, and derivations on C*-algebras, Lie C*-algebras and JC*-algebras associated with the bi-additive functional inequalities. Moreover, we study bihomomorphisms in C*-ternary algebras and C*-triple systems, and biderivations on C*-ternary algebras and C*-triple systems associated with the above bi-additive functional inequality.
