Invariant von Neumann subalgebras of crossed products and tensor products

Tattwamasi Amrutam, Artem Dudko, Yongle Jiang +1

Let $Γ$ be a countable discrete group acting on a tracial von Neumann algebra $(Q, τ_{Q})$ in a trace-preserving way. We study invariant von Neumann subalgebras of $Q ⋊ Γ$ and of…

Non-commutative Factor theorem for tensor products of lattices in product groups

Tattwamasi Amrutam, Yongle Jiang, Shuoxing Zhou

We establish a non-commutative version of the Intermediate Factor Theorem for crossed products associated with product lattices. Given an irreducible lattice $Γ< G= G_1 \times \dot…
