Glauber dynamics on the Erdős-Rényi random graph
Frank den Hollander, Oliver Jovanovski
We investigate the effect of disorder on the Curie-Weiss model with Glauber dynamics. In particular, we study metastability for spin-flip dynamics on the Erdős-Rényi random graph $…
Metastability on the hierarchical lattice
Frank den Hollander, Oliver Jovanovski
We study metastability for Glauber spin-flip dynamics on the -dimensional hierarchical lattice with hierarchical levels. Each vertex carries an Ising spin that can take the…
Metastability for Glauber dynamics on random graphs
Sander Dommers, Frank den Hollander, Oliver Jovanovski +1
In this paper we study metastable behaviour at low temperature of Glauber spin-flip dynamics on random graphs. We fix a large number of vertices and randomly allocate edges accordi…
Metastability for the Ising Model on the hypercube
Oliver Jovanovski
We consider Glauber dynamics for the low-temperature, ferromagnetic Ising Model set on the n-dimensional hypercube. We derive precise asymptotic results for the crossover time (the…
Convergence Rates for Hierarchical Gibbs Samplers
Oliver Jovanovski, Neal Madras
We establish some results for the rate of convergence in total variation of a Gibbs sampler to its equilibrium distribution. This sampler is motivated by a hierarchical Bayesian in…
Convergence bound in total variation for an image restoration model
Oliver Jovanovski
We consider a stochastic image restoration model proposed by A. Gibbs (2004), and give an upper bound on the time it takes for a Markov chain defined by this model to be ε- close i…
