When A ∈ B(H) and B ∈ B(K) are given, we denote by M C the operator matrix acting on the infinite- . In this paper, for given A and B, the sets C∈B l (K,H) Οƒ l (M C ), C∈Inv(K,H) Οƒ l (M C ) and C∈Inv(K,H) Οƒ l (M C ) are determined, where Οƒ l (T ), B l (K, H) and Inv(K, H) denote, respectively, the
