Gerstenhaber type structures on Davydov-Yetter cohomology with coefficients

Mamta Balodi, Abhishek Banerjee, Surjeet Kour

We obtain Gerstenhaber type structures on Davydov-Yetter cohomology with coefficients in half-braidings for a monoidal functor. Our approach uses a formal analogy between half-brai…

Comodule theories in Grothendieck categories and relative Hopf objects

Mamta Balodi, Abhishek Banerjee, Surjeet Kour

We develop the categorical algebra of the noncommutative base change of a comodule category by means of a Grothendieck category . We describe when the resulting catego…

Adjunctions between Eilenberg-Moore categories and a PBW-type theorem

Mamta Balodi, Abhishek Banerjee, Anita Naolekar

Recently, Dotsenko and Tamaroff have shown that a morphism of of monads over a category satisfies the PBW-property if and only if it makes int…

Categories of modules, comodules and contramodules over representations

Mamta Balodi, Abhishek Banerjee, Samarpita Ray

We study and relate categories of modules, comodules and contramodules over a representation of a small category taking values in (co)algebras, in a manner similar to modules over…

Fredholm modules over categories, Connes periodicity and classes in cyclic cohomology

Mamta Balodi, Abhishek Banerjee

We replace a ring with a small -linear category , seen as a ring with several objects in the sense of Mitchell. We introduce Fredholm modules over this cate…

Cyclic cohomology of entwining structures

Mamta Balodi, Abhishek Banerjee

In this paper, we introduce and study a cyclic cohomology theory for an entwining structure over a field . We then provide a complete description…

Categorified Fredholm Modules and Chern Characters

Mamta Balodi, Abhishek Banerjee

In this paper, we continue our program of systematic categorification of the Noncommutative Differential Geometry of Connes. We replace a ring with a small -linear categ…

BV-operators and secondary Hochschild complex

Mamta Balodi, Abhishek Banerjee, Anita Naolekar

We introduce the notion of a BV-operator on a homotopy -algebra such that the Gerstenhaber bracket on …

Cycles over DGH-semicategories and pairings in categorical Hopf-cyclic cohomology

Mamta Balodi, Abhishek Banerjee

Let be a Hopf algebra and let be a Hopf-module category. We describe the cocycles and coboundaries for the Hopf cyclic cohomology of , which corres…

Entwined modules over linear categories and Galois extensions

Mamta Balodi, Abhishek Banerjee, Samarpita Ray

In this paper, we study modules over quotient spaces of certain categorified fiber bundles. These are understood as modules over entwining structures involving a small -linear c…

Cohomology of modules over -categories and co--categories

Mamta Balodi, Abhishek Banerjee, Samarpita Ray

Let be a Hopf algebra. We consider -equivariant modules over a Hopf module category as modules over the smash extension . We construct Grothendi…

Morita invariance of equivariant and Hopf-cyclic cohomology of module algebras over Hopf algebroids

Mamta Balodi

We investigate the equivariant and Hopf-cyclic cohomology of module algebras over Hopf algebroids and derive their Morita invariance. For this, we use the tools developed by McCart…

On Boolean intervals of finite groups

Mamta Balodi, Sebastien Palcoux

We prove a dual version of Øystein Ore's theorem on distributive intervals in the subgroup lattice of finite groups, having a nonzero dual Euler totient . For any Boolean gr…
