Streszczenie
We 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.
