Return probability on Bienaymé-Galton-Watson trees and spectral asymptotics of sparse Erdős-Rényi random graphs

Markus Heydenreich, Peter Müller, Sara Terveer

We derive an upper bound for the annealed return probability of the simple random walk on supercritical Bienaymé-Galton-Watson trees. The bound decays subexponentially in time $t$ …

A note on Galois groups of linearized polynomials

Peter Müller

Let $L (X)$ be a monic $q$ -linearized polynomial over $F_{q}$ of degree $q^{n}$ , where $n$ is an odd prime. Recently Gow and McGuire showed that the Galois group of $L (X) / X - t$ over the…

On transitive sets of derangements in primitive groups

Peter Müller

We construct a primitive permutation action of the Steinberg triality group $^{3} D_{4} (2)$ of degree $4064256$ and show that there are distinct points $α, β$ such that there is no deran…
