A note on forbidding clique immersions [Elektronski vir]DeVos, Matt ...Robertson and Seymour proved that the relation of graph immersion is well-quasi-ordered for finite graphs. Their proof uses the results of graph minors theory. Surprisingly, there is a very short ... proof of the corresponding rough structure theorem for graphs without ▫$K_t$▫-immersions; it is based on the Gomory-Hu theorem. The same proof also works to establish a rough structure theorem for Eulerian digraphs without ▫$\vec{K}_t$▫-immersions, where ▫$\vec{K}_t$▫ denotes the bidirected complete digraph of order ▫$t$▫.Source: The Electronic journal of combinatorics [Elektronski vir]. - ISSN 1077-8926 (Vol. 20, no. 3, 2013, P55 (5 str.))Type of material - e-articlePublish date - 2013Language - englishCOBISS.SI-ID - 16924505
