Tight constructions for reconfigurations of independent transversals

Ronen Wdowinski

For a graph $G$ and partition $U$ of its vertex set, an independent transversal of $(G, U)$ is an independent set of $G$ that contains one vertex from each bloc…

Sampling from the antiferromagnetic Ising model on bipartite, regular expander graphs

Anna Geisler, Mihyun Kang, Michail Sarantis +1

The antiferromagnetic Ising model samples subsets of vertices of a graph with weight decaying exponentially in the number of edges induced. We study the problem of sampling from th…

Block-weighted random graphs: planar and beyond

Mihyun Kang, Zéphyr Salvy, Ronen Wdowinski

We investigate random connected graphs from a block-stable class whose distribution is weighted based on the number of $2$ -connected components, or blocks. This includes the class…
