$h$ -cobordisms between $1$ -connected manifolds with boundary

Ansel Goh

We classify $h$ -cobordisms between compact simply-connected $4$ -manifolds with boundary in both the smooth and topological categories. This extends a result of Kreck, which proved…

A decomposition theorem for balanced measures

Gregory Baimetov, Ryan Bushling, Ansel Goh +3

Let $G = (V, E)$ be a connected graph. A probability measure $μ$ on $V$ is called "balanced" if it has the following property: if $T_{μ} (v)$ denotes the "earth mover's" cost of transp…

On the image of graph distance matrices

William Dudarov, Noah Feinberg, Raymond Guo +5

Let $G = (V, E)$ be a finite, simple, connected, combinatorial graph on $n$ vertices and let $D \in R^{n \times n}$ be its graph distance matrix $D_{ij} = d (v_{i}, v_{j})$ . Stein…

Cosine Sign Correlation

Shilin Dou, Ansel Goh, Kevin Liu +2

Fix ${a_{1}, \dots, a_{n}} \subset N$ , and let $x$ be a uniformly distributed random variable on $[0, 2 π]$ . The probability $P (a_{1}, \dots, a_{n})$ that $\co…

Bounds in simple hexagonal lattice and classification of 11-stick knots

Yueheng Bao, Ari Benveniste, Marion Campisi +4

The stick number and the edge length of a knot type in the simple hexagonal lattice (sh-lattice) are the minimal numbers of sticks and edges required, respectively, to construct a…
