Selfless C*-correspondences, operator valued C*-probability spaces and completely positive maps

David Gao, Marius Junge, Srivatsav Kunnawalkam Elayavalli +2

We develop a general theory of selflessness for C*-correspondences, with several applications. Specializing this theory to completely positive maps, in particular to conditional ex…

Selfless reduced amalgamated free products and HNN extensions

David Gao, Srivatsav Kunnawalkam Elayavalli, Gregory Patchell +1

We find a general family of selfless inclusions in reduced amalgamated free products of C*-algebras. Apart from generalizing prior works due to McClanahan, Ivanov and Omland, our w…

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…

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…

Sequential commutation in tracial von Neumann algebras

Srivatsav Kunnawalkam Elayavalli, Gregory Patchell

Recall that a unitary in a tracial von Neumann algebra is Haar if for all . We introduce and study a new Borel equivalence relation on the set…
