Multislant matrices and Jacobi--Trudi determinants over finite fields

Omesh Dhar Dwivedi, Jonah Blasiak, Darij Grinberg

The problem of counting the $F_{q}$ -valued points of a variety has been well-studied from algebro-geometric, topological, and combinatorial perspectives. We explore a combin…

On the rank of Hankel matrices over finite fields

Omesh Dhar Dwivedi, Darij Grinberg

Given three nonnegative integers $p, q, r$ and a finite field $F$ , how many Hankel matrices $(x_{i + j})_{0 \leq i \leq p, 0 \leq j \leq q}$ over $F$ have rank $\leq r$ ? Thi…
