Defective coloring is perfect for minors
Chun-Hung Liu
The defective chromatic number of a graph class is the infimum such that there exists an integer such that every graph in this class can be partitioned into at most ind…
Homomorphism counts in robustly sparse graphs
Chun-Hung Liu
For a fixed graph and for arbitrarily large host graphs , the number of homomorphisms from to and the number of subgraphs isomorphic to contained in have bee…
Asymptotic Dimension of Minor-Closed Families and Assouad-Nagata Dimension of Surfaces
Marthe Bonamy, Nicolas Bousquet, Louis Esperet +4
The asymptotic dimension is an invariant of metric spaces introduced by Gromov in the context of geometric group theory. In this paper, we study the asymptotic dimension of metric…
Well-quasi-ordering digraphs with no long alternating paths by the strong immersion relation
Chun-Hung Liu, Irene Muzi
Nash-Williams' Strong Immersion Conjecture states that graphs are well-quasi-ordered by the strong immersion relation. That is, given infinitely many graphs, one graph contains ano…
Asymptotic dimension of minor-closed families and beyond
Chun-Hung Liu
The asymptotic dimension of metric spaces is an important notion in geometric group theory introduced by Gromov. The metric spaces considered in this paper are the ones whose under…
Immersion and clustered coloring
Chun-Hung Liu
Hadwiger and Hajós conjectured that for every positive integer , -minor free graphs and -topological minor free graphs are properly -colorable, respectively…
