Model Theory of General von Neumann Algebras II: Group Actions and Crossed Products
Jananan Arulseelan
Expanding on previous work of the author, we initiate the model theoretic study of W-dynamical systems. We axiomatize continuous weight-preserving group actions of on von N…
Model Theory of General von Neumann Algebras I: Generalized Ocneanu Ultraproducts
Jananan Arulseelan
This paper collates, presents, and expands upon technology and results obtained as part of the author's PhD thesis. We generalize work done in the -finite setting by the author,…
Totally Bounded Elements in W*-probability Spaces
Jananan Arulseelan, Isaac Goldbring, Bradd Hart +1
We introduce the notion of a totally (-) bounded element of a W*-probability space and, borrowing ideas of Kadison, give an intrinsic characterization of the -subal…
On the Elementary Equivalence of Group Factors
Jananan Arulseelan
We use techniques of distortion systems, introduced by James Hanson to show that any two elementarily equivalent infinite discrete ICC groups give rise to elementarily equivalent g…
