On a conjecture of King-Tollu-Toumazet for rectangular Kostka coefficients

Deepanshu Prasad

A conjecture of King, Tollu and Toumazet predicts the behavior of small Littlewood--Richardson coefficients under stretching: if $c_{λ, μ}^{ν} = 3$ , then $c_{M λ, M μ}^{M ν}$ equals $2 M + 1$ …

Growth of infinite frieze patterns of affine type

Karin Baur, Anna Felikson, Deepanshu Prasad +2

We analyse the growth coefficients of infinite frieze patterns arising from cluster algebras using cluster modular groups and cluster categories. For a fixed cluster category of af…

Counting 3-way contingency tables via quiver semi-invariants

Calin Chindris, Deepanshu Prasad

Let $T_{a, b}$ be the number of $3$ -way contingency tables of size $m \times n \times p$ with two of its three plane-sum margins fixed by $\mathbf{a}=(a_1…

Galois Coverings, $τ$ -Rigidity and Mutations

Charles Paquette, Deepanshu Prasad, David Wehlau

For an algebraically closed field $K$ , we consider a Galois $G$ -covering $B \to A$ between locally bounded $K$ -categories given by bound quive…

Semi-Invariant Rings: UFD and Codimension One Orbits

Charles Paquette, Deepanshu Prasad, David Wehlau

Let $A$ be a finite dimensional associative $K$ -algebra over an algebraically closed field $K$ of characteristic zero. To $A$ , we can associate its basic form tha…
