Positivstellensatz for C*-tensor categories
Kajal Das, Mainak Ghosh, Shamindra Ghosh
We explore semi-pre-C*-algebras in the context of rigid semisimple C*-tensor categories and using techniques from annular representations, we extend Ozawa's criterion for property…
On Ahn-Hendrey-Kim-Oum question for twin-width of graphs with 6 vertices
Kajal Das
Twin-width is a recently introduced graph parameter for finite graphs. It is an open problem to determine whether there is an -vertex graph having twin-width at least (due…
On super-rigidity of Gromov's random monster group
Kajal Das
In this article, we show super-rigidity of Gromov's random monster group. We prove that any morphism from Gromov's random monster group to the group has finite imag…
Computation of twin-width of graphs
Kajal Das
Twin-width is a recently introduced graph parameter. In this article, we compute twin-width of various finite graphs. In particular, we prove that the twin-widths of finite graphs…
From the coarse geometry of warped cones to the measured coupling of groups
Kajal Das
In this article, we prove that if two warped cones corresponding to two finitely generated groups with free, isometric, measure-preserving, actions on two compact metric spaces wit…
Invariance of non-vanishing of first -cohomology under -Measured Equivalence
Kajal Das
The first -cohomology is an algebro-analytical object attached to a finitely generated discrete group and introduced by M. Gromov. It is well known that it is invariant under…
From the geometry of box spaces to the geometry and measured couplings of groups
Kajal Das
In this paper, we prove that if two `box spaces' of two residually finite groups are coarsely equivalent, then the two groups are `uniform measured equivalent' (UME). More generall…
Integrable measure equivalence and the central extension of surface groups
Kajal Das, Romain Tessera
Let be a surface group of genus . It is known that the canonical central extension and the direct product are quasi-isometric. It…
