The monotone labelling method in spectral graph theory
Monotone labelling is a technique originated from an ancient joint work with Arnab Sen and Balint Virag originally designed to upper bound the mass of atoms in the spectrum of infinite random trees. It was recently found that it could be used to study the log Hölder regularity of the spectral measure of a large class of (possibly random) operators invariant under a group action. This has led to striking new results.
In this talk, I will review these recent progresses and explain how this method works. Talk partially based on a joint work with Wenbo Li and Joe Thomas.
November 18: Daniel Loughran (University of Bath, UK)

About the banner image:
The banner image is based on the identity element of the sandpile group of a grid graph. The random algebraic objects given by the sandpile groups of random graphs turns out to have fascinating connections to algebraic number theory, related to the Cohen-Lenstra conjectures for class groups of number fields.
