The perturbation for the Brow der's theorem of operator matrix
Wang Bi-y · Journal of Shandong University · 2014
Let T = (A B 0 JA*J) ∈B( H⊕H),where A,B∈B( H),conjugation J is an antilinear operator on H,which satisfies J2= I and〈Jx,Jy〉=〈y,x〉for all x,y∈H. The stability of the single valued extension property and the Browder's theorem for T under compact perturbations are explored.
