Counting independent sets in percolated graphs via the Ising model

Anna Geisler, Mihyun Kang, Michail Sarantis +1

Given a graph , we form a random subgraph by including each edge of independently with probability . We provide an asymptotic expansion of the expected number of in…

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…

Majority bootstrap percolation on the permutahedron and other high-dimensional graphs

Maurício Collares, Joshua Erde, Anna Geisler +1

Majority bootstrap percolation is a model of infection spreading in networks. Starting with a set of initially infected vertices, new vertices become infected once half of their ne…

Counting independent sets in expanding bipartite regular graphs

Maurício Collares, Joshua Erde, Anna Geisler +1

In this paper we provide an asymptotic expansion for the number of independent sets in a general class of regular, bipartite graphs satisfying some vertex-expansion properties, ext…

Universal behaviour of majority bootstrap percolation on high-dimensional geometric graphs

Maurício Collares, Joshua Erde, Anna Geisler +1

Majority bootstrap percolation is a monotone cellular automata that can be thought of as a model of infection spreading in networks. Starting with an initially infected set, new ve…
