-saturated graphs with small spectral radius

Jaehoon Kim, Seog-Jin Kim, Alexandr V. Kostochka +1

For a graph , a graph is -saturated if does not contain as a subgraph but for any , contains . In this note, we prove a sharp lowe…

The Alon-Tarsi number of -minor-free graphs

Toshiki Abe, Seog-Jin Kim, Kenta Ozeki

In this paper, we show the following three theorems. Let be a -minor-free graph. Then Alon-Tarsi number of is at most , there exists a matching of such that…

On list 3-dynamic coloring of near-triangulations

Ruijuan Gu, Seog-Jin Kim, Yulai Ma +1

An -dynamic -coloring of a graph is a proper -coloring such that for any vertex , there are at least distinct colors in . The -dyn…

Planar graphs without 7-cycles and butterflies are DP-4-colorable

Seog-Jin Kim, Runrun Liu, Gexin Yu

DP-coloring (also known as correspondence coloring) is a generalization of list coloring, introduced by Dvořák and Postle in 2017. It is well-known that there are non-4-choosable p…

Coloring squares of graphs with mad constraints

Hervé Hocquard, Seog-Jin Kim, Théo Pierron

A proper vertex -coloring of a graph is an assignment of colors to the vertices of the graph such that no two adjacent vertices are associate…
