A proof of Andersen's rainbow path conjecture for large

Candida Bowtell, Richard Montgomery, Alp Müyesser +1

We show that, for sufficiently large , every properly edge-coloured -vertex complete graph contains a path with vertices which uses each colour at most once (that is, a…

Nearly-uniform degree distributions in spanning subgraphs

Richard Montgomery, Alexey Pokrovskiy, Benny Sudakov

We show that, when , every -regular -vertex graph contains a spanning subgraph whose degree distribution is nearly uniform, i.e., for each , there are…

Towards Graham's rearrangement conjecture via rainbow paths

Matija Bucić, Bryce Frederickson, Alp Müyesser +2

We study an old question in combinatorial group theory which can be traced back to a conjecture of Graham from 1971. Given a group , and some subset , is it poss…

Chi-boundedness of graphs containing no cycles with chords

Joonkyung Lee, Shoham Letzter, Alexey Pokrovskiy

We prove that the family of graphs containing no cycle with exactly -chords is -bounded, for large enough or of form with an integer. This ve…

Decomposing cubic graphs into isomorphic linear forests

Gal Kronenberg, Shoham Letzter, Alexey Pokrovskiy +1

A common problem in graph colouring seeks to decompose the edge set of a given graph into few similar and simple subgraphs, under certain divisibility conditions. In 1987 Wormald c…

Size-Ramsey numbers of tight paths

Shoham Letzter, Alexey Pokrovskiy, Liana Yepremyan

The -colour size-Ramsey number of a hypergraph is the minimum number of edges in a hypergraph whose every -edge-colouring contains a monochromatic copy of . We sho…
