(2023). Quasidiagonal weighted shifts on directed trees. Studia Mathematica, 273(2), 101–138. https://doi.org/10.4064/sm220830-7-8We investigate quasidiagonality of weighted shifts on directed trees. We concentrate mainly on a subclass of weighted shifts operators called adjacency operators. In particular, we provide equivalent conditions for quasidiagonality of adjacency operators in terms of the structure of directed trees.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/quasidiagonal operatorsweighted shifts on directed treesadjacency operatorsArticle
