Let X,Y be Banach spaces, and upper triangular operator matrices acting on X?Y are studied. Given bounded operators A, B, we obtain several equivalent conditions forMX = [A X 0 B] to be a left Browder, a right Browder and a Browder operator for some bounded unknown operator X. Finally, an example is presented to illustrate the main conclusion.
