Exotic full factors via weakly coarse bimodules

David Gao, David Jekel, Srivatsav Kunnawalkam Elayavalli +1

We are able to explicitly compute the bimodule structure of von Neumann algebra inclusions in handle constructions, which arise as inductive limits of iterated amalgamated free pro…

Selfless Inclusions of C*-Algebras

Ben Hayes, Srivatsav Kunnawalkam Elayavalli, Gregory Patchell +1

We introduce and study a natural notion of selflessness for inclusions of C*-probability spaces, which in particular implies that all intermediate C*-algebras are selfless in the s…

Some remarks on decay in countable groups and amalgamated free products

Srivatsav Kunnawalkam Elayavalli, Gregory Patchell, Lizzy Teryoshin

In this note, we first study the notion of subexponential decay (SD) for countable groups with respect to a length function, which generalizes the well-known rapid decay (RD) prope…

3-handle construction on II factors

David Gao, Srivatsav Kunnawalkam Elayavalli, Gregory Patchell

We find a subtle modification to the construction of Chifan-Ioana-Kunnawalkam Elayavalli, which yields a drastic simplification of the proof of the existence of two non Gamma non e…

Strict comparison in reduced group -algebras

Tattwamasi Amrutam, David Gao, Srivatsav Kunnawalkam Elayavalli +1

We prove that for every , the reduced group -algebras of the countable free groups have strict comparison. Our method works in a general setting…
