Odd minors or odd immersions in graphs with independence number two

Antonia Bermúdez, Bruno L. Netto, Daniel A. Quiroz

Kühn, Sauermann, Steiner and Wigderson recently disproved the Odd Hadwiger Conjecture, even for graphs with independence number 2. For this class of graphs the conjecture is known…

Odd Hadwiger number and graph products

Henry Echeverría, Andrea Jiménez, Suchismita Mishra +2

The Odd Hadwiger number of a graph $G$ is the largest integer $r$ such that $G$ has a clique of size $r$ as an odd minor. In this paper, we investigate how large is the Odd Hadwige…

Homomorphism counting for immersion-closed classes is not isomorphism

Andrea Jiménez, Benjamin Moore, Daniel A. Quiroz +1

Lovász proved that two graphs $G$ and $H$ are isomorphic if $hom (K, G) = hom (K, H)$ for all graphs $K$ , where $hom (G_{1}, G_{2})$ denotes the number of homomorphisms from $G_{1}$ to $G_2…
