An 18-colour bound for locally irregular decompositions

Carla Negri Lintzmayer, Guilherme Oliveira Mota, Maycon Sambinelli +1

A graph is locally irregular if adjacent vertices have distinct degrees. A graph G is decomposable if its edge set can be decomposed into locally irregular graphs, and its locally…

Proper conflict-free 7-coloring of planar graphs

A. Jiménez, C. N. Lintzmayer, M. Sambinelli

A proper conflict-free coloring is a proper vertex coloring in which every nonisolated vertex has a color occurring uniquely in its open neighborhood. We prove that every graph wit…

Immersions of large cliques in graphs with independence number 2 and bounded maximum degree

Fábio Botler, Cristina G. Fernandes, Carla N. Lintzmayer +4

An immersion of a graph in a graph is a minimal subgraph of for which there is an injection and a set of edge-disjoint paths $\{P_e:…

Towards Gallai's path decomposition conjecture

Fabio Botler, Maycon Sambinelli

A path decomposition of a graph G is a collection of edge-disjoint paths of G that covers the edge set of G. Gallai (1968) conjectured that every connected graph on n vertices admi…

Perfect digraphs

Cândida Nunes da Silva, Orlando Lee, Maycon Sambinelli

Let be a digraph. Given a set of vertices , an -path partition of is a collection of paths of such that $\{V(P) \colon P \in \mathcal…
