M Isometric Elementary Operators On Standard Operator Algebras

This paper mainly study the elementary operators τ(A,B)and σ(A,B)defined on a self-adjoint operator algebra.We give some sufficient and necessary conditions to describe m isometries which defined on τ(A,B)and σ(A,B).Moreover,we provide a sufficient and necessary conditions to show m isometries which defined on τ(A,B)and C*-algebra.
