Characterizations of Matrix Valued Asymmetric Truncated Toeplitz Operators
Published 29 Mar 2021 in math.FA and math.OA | (2103.15719v3)
Abstract: We characterize matrix-valued asymmetric truncated Toeplitz operators (which are compressions of multiplication operators acting between two possibly different model spaces) by using compressed shifts, modified compressed shifts and shift invariance.
