Operators Induced by Graphs
Ilwoo Cho, Palle E. T. Jorgensen
In this paper, we consider certain elements in von Neumann algebras generated by graph groupoids. In particular, we are interested in finitely supported elements, called graph oper…

Toeplitz Operators in Hilbert Space over Graphs
Ilwoo Cho, Palle E. T. Jorgensen
In this paper, we consider the relation between Toeplitz operators and elements in von Neumann algebras generated by certain graph groupoids.
