Bounding the Chromatic Number of Dense Digraphs by Arc Neighborhoods

Combinatorica, 2023
The chromatic number of a directed graph is the minimum number of induced acyclic subdigraphs that cover its vertex set, and accordingly, the chromatic number of a tournament is the minimum number of transitive subtournaments that cover its vertex set ...

Distributed finite‐time optimization algorithms for multi‐agent systems under directed graphs

International Journal of Robust and Nonlinear Control, 2023
Existing distributed finite‐time optimization algorithms for continuous‐time multi‐agent systems require either undirected graphs or weight balanced digraphs, and distributed finite‐time optimization problems for weight unbalanced digraphs are still ...

Well-Quasi-Ordering Eulerian Digraphs Embeddable in Surfaces by Strong Immersion

arXiv.org
We prove that for every surface $\Sigma$, the class of Eulerian directed graphs that are Eulerian embeddable into $\Sigma$ (in particular they have degree at most $4$) is well-quasi-ordered by strong immersion. This result marks one of the most versatile
