Abstract:

A conjecture akin to Hadwiger's conjecture posits that every graph G contains an immersion of the complete graph Kχ(G). Vergara showed that, for every n-vertex graph G with independence number two, this is equivalent to saying that G contains an immersion of the complete graph on [Formula presented] vertices. Recently, Botler et al. showed that every n-vertex graph G with α(G)=2 contains every complete bipartite graph on [Formula presented] vertices as an immersion. In this paper, we give a much simpler proof of this result. © 2025 Elsevier B.V.
