On possible values of the interior angle between intermediate subalgebras
Ved Prakash Gupta, Deepika Sharma
We show that all values in the interval can be attained as the interior angle between intermediate subalgebras (as introduced in [3]) of a certain inclusion of simp…
A few remarks on Pimsner-Popa bases and regular subfactors of depth 2
Keshab Chandra Bakshi, Ved Prakash Gupta
We prove that a finite index regular inclusion of -factors with commutative first relative commutant is always a crossed product subfactor with respect to a minimal action of…
Lattice of intermediate subalgebras
Keshab Chandra Bakshi, Ved Prakash Gupta
Analogous to subfactor theory, employing Watatani's notions of index and -basic construction of certain inclusions of -algebras, (a) we develop a Fourier theory (consisti…
On orthogonal systems, two-sided bases and regular subfactors
Keshab Chandra Bakshi, Ved Prakash Gupta
We prove that a regular subfator of type with finite Jones index always admits a two-sided Pimsner-Popa basis. This is preceeded by a pragmatic revisit of Popa's notion of o…
A note on irreducible quadrilaterals of factors
Keshab Chandra Bakshi, Ved Prakash Gupta
Given any finite index quadrilateral of -factors, the notions of interior and exterior angles between and were introduced in \cite{BDLR2017}. We determ…
On Banach space projective tensor product of -algebras
Ved Prakash Gupta, Ranjana Jain
We analyze certain algebraic structures of the Banach space projective tensor product of -algebras which are comparable with their known counterparts or the Haagerup tensor pr…
On closed Lie ideals of certain tensor products of C*-algebras II
Ved Prakash Gupta, Ranjana Jain, Bharat Talwar
We identify all closed Lie ideals of and , where is either the Haagerup tensor product, the Banach space projective tensor product…
On closed Lie ideals of certain tensor products of -algebras
Ranjana Jain, Ved Prakash Gupta
For a simple -algebra and any other -algebra , it is proved that every closed ideal of is a product ideal if either is exact or is nuc…
Operator System Nuclearity via -envelopes
Ved Prakash Gupta, Preeti Luthra
We prove that an operator system is (min, ess)-nuclear if its C*-envelope is nuclear. This allows us to deduce that an operator system associated to a generating set of countable d…
Planar Algebra of the Subgroup-Subfactor
Ved Prakash Gupta
We give an identification between the planar algebra of the subgroup-subfactor and the -invariant planar subalgebra of the planar algebra of th…
