Equivalence after extension and matricial coupling coincide with Schur coupling, on separable Hilbert spaces
(Elsevier, 2013)It is known that two Banach space operators that are Schur coupled are also equivalent after extension, or equivalently, matricially coupled. The converse implication, that operators which are equivalent after extension ... -
Equivalence after extension and Schur coupling coincide for inessential operators
(Elsevier, 2018)In recent years the coincidence of the operator relations equivalence after extension (EAE) and Schur coupling (SC) was settled for the Hilbert space case. For Banach space operators, it is known that SC implies EAE, but ... -
Equivalence after extension and Schur Coupling for relatively regular operators
(Springer, 2020)It was recently shown in Ter Horst et al. (Bull Lond Math Soc 51:1005–1014, 2019) that the Banach space operator relations Equivalence After Extension (EAE) and Schur Coupling (SC) do not coincide by characterizing these ... -
Equivalence after extension for compact operators on Banach spaces
(Elsevier, 2015)In recent years the coincidence of the operator relations equivalence after extension and Schur coupling was settled for the Hilbert space case, by showing that equivalence after extension implies equivalence after one-sided ...
