A reconfigurations analogue of Brooks' Theorem and its consequences

C Feghali, M Johnson, D Paulusma - Journal of graph theory, 2016 - Wiley Online Library
Let G be a simple undirected connected graph on n vertices with maximum degree Δ.
Brooks' Theorem states that G has a proper Δ‐coloring unless G is a complete graph, or a …

A catlin-type theorem for graph partitioning avoiding prescribed subgraphs

Y Rowshan, A Taherkhani - Discrete Mathematics, 2022 - Elsevier
As an extension of the Brooks theorem, Catlin in 1979 showed that if H is neither an odd
cycle nor a complete graph with maximum degree Δ (H), then H has a vertex Δ (H)-coloring …

Brooks's theorem

M Stiebitz, B Toft - Topics in Chromatic Graph Theory, 2015 - Springer
Brooks' Theorem from 1941 is a cornerstone in graph theory. Until then graph coloring
theory was centered around planar graphs and the four color problem. Brooks' Theorem was …

Vertex partition of hypergraphs and maximum degenerate subhypergraphs

T Schweser, M Stiebitz - arXiv preprint arXiv:1807.02308, 2018 - arxiv.org
In 2007 Matamala proved that if $ G $ is a simple graph with maximum degree $\Delta\geq
3$ not containing $ K_ {\Delta+ 1} $ as a subgraph and $ s, t $ are positive integers such that …

Vertex Partitions and Maximum $\G $-free Subgraphs

Y Rowshan - arXiv preprint arXiv:2207.04964, 2022 - arxiv.org
For a given graph $ H $ and the graphical properties $ P_1, P_2,\ldots, P_k $, we say the
graph $ H $ has a $(V_1, V_2,\ldots, V_k) $-decomposition, if for each $ i\in [k] $, the …
