Eulerian and even-face ribbon graph minors

Discrete Mathematics, 2020
In this paper, we introduce Eulerian and even-face ribbon graph minors. These minors preserve Eulerian and even-face properties of ribbon graphs, respectively.

Graph minors and linkages

Journal of Graph Theory, 2005
AbstractBollobás and Thomason showed that every 22k‐connected graph is k‐linked. Their result used a dense graph minor. In this paper, we investigate the ties between small graph minors and linkages. In particular, we show that a 6‐connected graph with a K minor is 3‐linked.

Directed Graph Minors and Serial-Parallel Width [PDF]

open access: yesInternational Symposium on Mathematical Foundations of Computer Science, 2017
Graph minors are a primary tool in understanding the structure of undirected graphs, with many conceptual and algorithmic implications. We propose new variants of directed graph minors and directed graph embeddings, by modifying familiar definitions. For

Efficient Graph Minors Theory and Parameterized Algorithms for (Planar) Disjoint Paths

Treewidth, Kernels, and Algorithms, 2020
In the Disjoint Paths problem, the input consists of an n-vertex graph G and a collection of k vertex pairs, \(\{(s_i,t_i)\}_{i=1}^k\), and the objective is to determine whether there exists a collection \(\{P_i\}_{i=1}^k\) of k pairwise vertex-disjoint ...
