Weyl spectrum of the products of operators

국문 초록 (Abstract)

Let MC = (수식) be a 2×2 upper triangular operator matrix
acting on the Hilbert space H K and let σw(ㆍ) denote theWeyl spectrum.
We give the necessary and sufficient conditions for operators A and B
which [수식] holds for every C ∈ B(K, H). We also study the Weyl’s theorem for operator
matrices.
