Internal graphs of graph products of hyperfinite II-factors
Martijn Caspers, Enli Chen
In this paper, we show that for a graph from a class named H-rigid graphs, its subgraph , named the internal graph of , is an isomorphism invariant of the grap…

Rigid Graph Products
Matthijs Borst, Martijn Caspers, Enli Chen
We prove rigidity properties for von Neumann algebraic graph products. We introduce the notion of rigid graphs and define a class of II-factors named .…
