Renormalisation of Inhomogeneous Random Graphs

Luca Avena, Diego Garlaschelli, Rajat Subhra Hazra +1

We consider inhomogeneous random graphs in which vertices are assigned i.i.d.\ random weights, pairs of distinct vertices are connected by an edge independently with a probability…

Co-evolving vertex and edge dynamics in dense graphs

Siva Athreya, Frank den Hollander, Adrian Röllin

We consider a random graph in which vertices can have one of two possible colours. Each vertex switches its colour at a rate that is proportional to the number of vertices of the o…

Self-repellent branching random walk

Anton Bovier, Lisa Hartung, Frank den Hollander

We consider a system of particles performing a discrete-time binary branching random walk with independent standard normal increments subject to a penalty $\b$ for every pair of pa…

On the principal eigenvectors of random Markov matrices

Jacob Calvert, Frank den Hollander, Dana Randall

We analyze the invariant distributions of continuous-time and discrete-time random walks on randomly weighted complete digraphs. These distributions correspond to the principal lef…

Homogeneous nucleation for two-dimensional Kawasaki dynamics

Simone Baldassarri, Alexandre Gaudillière, Frank den Hollander +3

This is the third in a series of three papers in which we study a lattice gas subject to Kawasaki dynamics at inverse temperature in a large finite box $Λ_β\subset \mathbb…

Tame sparse exponential random graphs

Suman Chakraborty, Remco van der Hofstad, Frank den Hollander

In this paper, we obtain a precise estimate of the probability that the sparse binomial random graph contains a large number of vertices in a triangle. The estimate of log of this…
