Topological Zeta Functions of Matroids: Operations and Computations

Dawit Mengesha, Robert Miranda, Brian Sun

The topological zeta function of a matroid is a rational function as well as a valuative invariant of the matroid, encoding rich combinatorial information. We analyze topological z…

Twisted Alexander Polynomials and Fibered Classes in Ribbon Homology Cobordisms

Brian Sun

Let and be two compact 3-manifolds with empty or toroidal boundary. A 4-dimensional ribbon homology cobordism is a homologically trivial cobordism built with 1-handles…

Topology of augmented Bergman complexes

Elisabeth Bullock, Aidan Kelley, Victor Reiner +6

The augmented Bergman complex of a matroid is a simplicial complex introduced recently in work of Braden, Huh, Matherne, Proudfoot and Wang. It may be viewed as a hybrid of two wel…

On the probability of existence of a universal cycle or a universal word for a set of words

Herman Z. Q. Chen, Sergey Kitaev, Brian Y. Sun

A universal cycle, or u-cycle, for a given set of words is a circular word that contains each word from the set exactly once as a contiguous subword. The celebrated de Bruijn seque…

On some divisibility properties of binomial sums

Brian Y. Sun

In this paper, we consider two particular binomial sums \begin{align*} \sum_{k=0}^{n-1}(20k^2+8k+1){\binom{2k}{k}}^5 (-4096)^{n-k-1} \end{align*} and \begin{align*} \sum_{k=0}^{n-1…
