Denoising data reduction algorithm for Topological Data Analysis

Seonmi Choi, Semin Oh, Jeong Rye Park +1

Persistent homology is a central tool in topological data analysis, but its application to large and noisy datasets is often limited by computational cost and the presence of spuri…

Sharp conditions for the existence of an even $[a, b]$ -factor in a graph

Eun-Kyung Cho, Jong Yoon Hyun, Suil O +1

Let $a$ and $b$ be positive integers. An even $[a, b]$ -factor of a graph $G$ is a spanning subgraph $H$ such that for every vertex $v \in V (G)$ , $d_{H} (v)$ is even and $a \le d_H(v) \…

The weighted poset metrics and directed graph metrics

Jong Yoon Hyun, Hyun Kwang Kim, Jeong Rye Park

Etzion et al. introduced metrics on $F_{2}^{n}$ based on directed graphs on $n$ vertices and developed some basic coding theory on directed graph metric spaces. In this paper,…
