Quasidiagonality of direct sums of weighted shifts
Abstract
A necessary and sufficient condition is given for a finite direct sum of weighted shifts to be quasidiagonal. The condition is stated using a marked graph (a graph with a (0), (+), or ($-$) attached to its vertices) that can be associated with the direct sum.
