Abstract

Let XX be a complex Banach space with dimX3\dim X\geq3 and B(X)B(X) the algebra of all bounded linear operators on XX. Suppose ϕ:B(X)B(X)\phi:B(X)\longrightarrow B(X) is a surjective map satisfying the following property: Fix(AB)=Fix(ϕ(A)ϕ(B)),(A,BB(X))Fix(AB)=Fix(\phi(A)\phi(B)), (A, B\in B(X)). Then the form of ϕ\phi is characterized, where Fix(T)Fix(T) is the set of all fixed points of an operator TT.
