Abstract :
Let H and K be separable complex Hilbert spaces, and let B(H,K) be the space of bounded linear operators from H to K. If H=K we write B(H) for B(H,H).In this note we study separating vectors for separators on B(H bigoplusK) that have representations of the form(A C 0 B) where A inB(H),B inB(K) and C inB(K,H).
