Multiparameter colored partition category and the product of the reduced Kronecker coefficients

Volodymyr Mazorchuk, Shraddha Srivastava

We introduce and study a multiparameter colored partition category $C P a r (x)$ by extending the construction of the partition category, over an algebraically close…

Finite quotients of singular Artin monoids and categorification of the desingularization map

Helena Jonsson, Volodymyr Mazorchuk, Elin Persson Westin +3

We study various aspects of the structure and representation theory of singular Artin monoids. This includes a number of generalizations of the desingularization map and explicit p…

Jucys-Murphy elements of partition algebras for the rook monoid

Ashish Mishra, Shraddha Srivastava

Kudryavtseva and Mazorchuk exhibited Schur-Weyl duality between the rook monoid algebra $C R_{n}$ and the subalgebra $C I_{k}$ of the partition algebra $\mathbb{C} A_k(…

Schur Algebras for the Alternating Group and Koszul Duality

Thangavelu Geetha, Amritanshu Prasad, Shraddha Srivastava

We introduce the alternating Schur algebra $A S_{F} (n, d)$ as the commutant of the action of the alternating group $A_{d}$ on the $d$ -fold tensor power of an $n$ -dimensional $F$ -vector s…

On representation theory of partition algebras for complex reflection groups

Ashish Mishra, Shraddha Srivastava

This paper defines the partition algebra for complex reflection group $G (r, p, n)$ acting on $k$ -fold tensor product $(C^{n})^{\otimes k}$ , where $C^{n}$ is the reflect…
