Cycles with two blocks in $k$ -chromatic digraphs

Ringi Kim, Seog-Jin Kim, Jie Ma +1

Let $k$ and $ℓ$ be positive integers. A cycle with two blocks $c (k, ℓ)$ is an oriented cycle which consists of two internally (vertex) disjoint directed paths of lengths at le…

List 3-dynamic coloring of graphs with small maximum average degree

Seog-Jin Kim, Boram Park

An $r$ -dynamic $k$ -coloring of a graph $G$ is a proper $k$ -coloring such that for any vertex $v$ , there are at least $min {r, °_{G} (v)}$ distinct colors in $N_{G} (v)$ . The $r$ -dynami…

The Betti numbers of real toric varieties associated to Weyl chambers of type $B$

Suyoung Choi, Boram Park, Hanchul Park

We compute the (rational) Betti number of real toric varieties associated to Weyl chambers of type $B$ . Furthermore, we show that their integral cohomology is $p$ -torsion free for…
