Ceci n’est pas une œuvre de fiction. Cependant, toute ressemblance avec des théorèmes connus serait purement fortuite et le fruit du hasard.
We prove sharp rates of convergence to stationarity for a simple case of the Metropolis algorithm: the placement of a single disc of radius randomly into the interval . We find good approximations for the top eigenvalues and eigenvectors. The analysis gives rigorous proof for the careful numerical work in [DN04]. The micro-local techniques employed offer promise for the analysis of more realistic problems.
