Reconstruction for Colorings on Trees

Nayantara Bhatnagar, Juan Vera, Eric Vigoda +1

Consider $k$ -colorings of the complete tree of depth $ℓ$ and branching factor $Δ$ . If we fix the coloring of the leaves, as $ℓ$ tends to $\infty$ , for what range of $k$ is th…

Randomly coloring planar graphs with fewer colors than the maximum degree

Thomas P. Hayes, Juan C. Vera, Eric Vigoda

We study Markov chains for randomly sampling $k$ -colorings of a graph with maximum degree $Δ$ . Our main result is a polynomial upper bound on the mixing time of the single-site upd…
