Meta-Theorems for Cuttable Distributed Problems

Marthe Bonamy, Avinandan Das, Cyril Gavoille +3

We prove that given any -approximation LOCAL algorithm for Minimum Dominating Set (MDS) on planar graphs, we can construct an -round -approximation LOCAL algorit…

On Modular Edge Colourings of Graphs

Gaétan Berthe, Marthe Bonamy, Fábio Botler +5

Given a graph and an integer , let denote the minimum number of colours required to colour the edges of such that, in each colour class, the subgraph in…

Bipartite Turán number of paths and other trees

Marthe Bonamy, Théotime Leclere, Timothé Picavet

We solve a recent question of Caro, Patkós and Tuza by determining the exact maximum number of edges in a bipartite connected graph as a function of the longest path it contains a…

On cuts of small chromatic number in sparse graphs

Guillaume Aubian, Marthe Bonamy, Romain Bourneuf +2

For a given integer , let denote the supremum such that every sufficiently large graph with average degree less than admits a separator $X \subseteq…

Distributed Approximation Algorithms for Minimum Dominating Set in Locally Nice Graphs

Marthe Bonamy, Cyril Gavoille, Timothé Picavet +1

We give a new, short proof that graphs embeddable in a given Euler genus- surface admit a simple -round -approximation distributed algorithm for Minimum Dominating Set…

-Boundedness and Neighbourhood Complexity of Bounded Merge-Width Graphs

Marthe Bonamy, Colin Geniet

Merge-width, recently introduced by Dreier and Toruńczyk, is a common generalisation of bounded expansion classes and twin-width for which the first-order model checking problem r…
