McDuff superrigidity for group II factors
Juan Felipe Ariza Mejía, Ionuţ Chifan, Denis Osin +1
Developing new techniques at the interface of geometric group theory and von Neumann algebras, we identify the first examples of ICC groups whose von Neumann algebras are McDuf…
Revealing quantum operator scrambling via measuring Holevo information on digital quantum simulators
Bin Sun, Geng-Bin Cao, Xi-Dan Hu +1
Quantum operator scrambling describes the spreading of local operators into the whole system in the picture of Heisenberg evolution, which is often quantified by the operator size…
-Betti numbers of Dehn fillings
Nansen Petrosyan, Bin Sun
We initiate the study of the -Betti numbers of group-theoretic Dehn fillings. For a broad class of virtually special groups , we prove that the -Betti numbers of suffi…
Wreath-like products of groups and their von Neumann algebras III: Embeddings
Ionut Chifan, Adrian Ioana, Denis Osin +1
For a class of wreath-like product groups with property (T), we describe explicitly all the embeddings between their von Neumann algebras. This allows us to provide a continuum of…
Small cancellation and outer automorphisms of Kazhdan groups acting on hyperbolic spaces
I. Chifan, A. Ioana, D. Osin +1
We show that every finite group realizes as the outer automorphism group of an ICC hyperbolic group with Kazhdan property (T). This result complements the well-known theorem of Pau…
On the Refinement of Certain Statistics on Alternating Words
Chia-An Hsu, Hsu-Lin Chien, Han-Chun Chan +2
In this paper, we investigate statistics on alternating words under correspondence between ``possible reflection paths within several layers of glass'' and ``alternating words''. F…
