Counting on the variety of modules over the quantum plane

Yifeng Huang

Let $ζ$ be a fixed nonzero element in a finite field $F_{q}$ with $q$ elements. In this article, we count the number of pairs $(A, B)$ of $n \times n$ matrices over $\mathbb F_…

Continuously Increasing Subsequences of Random Multiset Permutations

Alexander Clifton, Bishal Deb, Yifeng Huang +2

For a word $π$ and integer $i$ , we define $L^{i} (π)$ to be the length of the longest subsequence of the form $i (i + 1) \dots j$ , and we let $L (π) := max_{i} L^{i} (π)$ . In this paper we esti…

Mutually annihilating matrices, and a Cohen--Lenstra series for the nodal singularity

Yifeng Huang

We give a generating function for the number of pairs of $n \times n$ matrices $(A, B)$ over a finite field that are mutually annihilating, namely, $A B = B A = 0$ . This generating functi…
