Multiparty equality in the local broadcast model

Louis Esperet, Jean-Florent Raymond

In this paper we consider the multiparty equality problem in graphs, where every vertex of a graph is given an input, and the goal of the vertices is to decide whether all inpu…

Local certification of geometric graph classes

Oscar Defrain, Louis Esperet, Aurélie Lagoutte +2

The goal of local certification is to locally convince the vertices of a graph that satisfies a given property. A prover assigns short certificates to the vertices of the g…

A quasi-optimal upper bound for induced paths in sparse graphs

Basile Couëtoux, Oscar Defrain, Jean-Florent Raymond

In 2012, NeÅ¡etřil and Ossona de Mendez proved that graphs of bounded degeneracy that have a path of order also have an induced path of order . In this paper…

Profile and neighbourhood complexity of graphs excluding a minor and tree-structured graphs

Laurent Beaudou, Jan Bok, Florent Foucaud +2

The \emph{-neighbourhood complexity} of a graph is the function counting, for a given integer , the largest possible number, over all vertex-subsets of size , of s…

Long induced paths and forbidden patterns: Polylogarithmic bounds

Julien Duron, Louis Esperet, Jean-Florent Raymond

Consider a graph with a long path . When is it the case that also contains a long induced path? This question has been investigated in general as well as within a number…

Long induced paths in sparse graphs and graphs with forbidden patterns

Julien Duron, Louis Esperet, Jean-Florent Raymond

Consider a graph with a path of order . What conditions force to also have a long induced path? As complete bipartite graphs have long paths but no long induced path…
