Phase coexistence and torpid mixing in the 3-coloring model on Z^d

David Galvin, Jeff Kahn, Dana Randall +1

We show that for all sufficiently large d, the uniform proper 3-coloring model (in physics called the 3-state antiferromagnetic Potts model at zero temperature) on Z^d admits multi…

Partitioning edge-coloured complete graphs into monochromatic cycles and paths

Alexey Pokrovskiy

A conjecture of Erdős, Gyárfás, and Pyber says that in any edge-colouring of a complete graph with r colours, it is possible to cover all the vertices with r vertex-disjoint monoch…

Cycles are strongly Ramsey-unsaturated

Jozef Skokan, Maya Stein

We call a graph H Ramsey-unsaturated if there is an edge in the complement of H such that the Ramsey number r(H) of H does not change upon adding it to H. This notion was introduce…

The fractional chromatic number of triangle-free subcubic graphs

David Ferguson, Tomáš Kaiser, Daniel Král'

Heckman and Thomas conjectured that the fractional chromatic number of any triangle-free subcubic graph is at most 14/5. Improving on estimates of Hatami and Zhu and of Lu and Peng…
