Clustered Colouring in Minor-Closed Classes
The clustered chromatic number of a class of graphs is the minimum integer k such that for some integer c every graph in the class is k-colourable with monochromatic components of size at most c. We prove that for every graph H , the clustered chromatic number of the class of H-minor-free graphs is tied to the tree-depth of H . In particular, if H has tree-depth t then every H-minor-free graph ...
متن کاملStructure in minor-closed classes of matroids
This paper gives an informal introduction to structure theory for minorclosed classes of matroids representable over a fixed finite field. The early sections describe some historical results that give evidence that well-defined structure exists for members of such classes. In later sections we describe the fundamental classes and other features that necessarily appear in structure theory for mi...
متن کاملToken Jumping in Minor-Closed Classes
Given two k-independent sets I and J of a graph G, one can ask if it is possible to transform the one into the other in such a way that, at any step, we replace one vertex of the current independent set by another while keeping the property of being independent. Deciding this problem, known as the Token Jumping (TJ) reconfiguration problem, is PSPACE-complete even on planar graphs. Ito et al. p...
متن کاملSome minor-closed classes of signed graphs
We define four minor-closed classes of signed graphs in terms of embeddability in the annulus, projective plane, torus, and Klein bottle. We give the full list of 20 excluded minors for the smallest class and make a conjecture about the largest class.
متن کاملSquare Roots of Minor Closed Graph Classes
Let G be a graph class. The square root of G contains all graphs whose square belong in G. We prove that if G is non-trivial and minor closed, then all graphs in its square root have carving-width bounded by some constant depending only on G. As a consequence, every square root of such a graph class has a linear time recognition algorithm.
