On the Minimal Edge Density of -free 6-critical Graphs

Wenbo Gao, Luke Postle

Kostochka and Yancey resolved a famous conjecture of Ore on the asymptotic density of -critical graphs by proving that every -critical graph satisfies $|E(G)| \geq (\frac…

Improved Bounds for Randomly Sampling Colorings via Linear Programming

Sitan Chen, Michelle Delcourt, Ankur Moitra +2

A well-known conjecture in computer science and statistical physics is that Glauber dynamics on the set of -colorings of a graph on vertices with maximum degree is r…

The structure of binary matroids with no induced claw or Fano plane restriction

Marthe Bonamy, Frantisek Kardos, Tom Kelly +2

An 'induced restriction' of a simple binary matroid is a restriction , where is a flat of . We consider the class of all simple binary matroids co…

Rapid mixing of Glauber dynamics for colorings below Vigoda's threshold

Michelle Delcourt, Guillem Perarnau, Luke Postle

A well-known conjecture in computer science and statistical physics is that Glauber dynamics on the set of -colorings of a graph on vertices with maximum degree is r…

Bounding by a fraction of for graphs without large cliques

Marthe Bonamy, Tom Kelly, Peter Nelson +1

The greedy coloring algorithm shows that a graph of maximum degree at most has chromatic number at most , and this is tight for cliques. Much attention has been devoted t…
