Merging for time-inhomogeneous Markov chains via Poincaré inequality
星期二, 7 五月, 2024 - 从 14:00 到 15:00
Résumé :
We study time-inhomogeneous Markov chains to obtain quantitative results on their asymptotic behavior. We use Poincaré inequalities. We assume that our Markov chain admits a finite invariant measure at each time and that the sequence of these invariant measures is non-decreasing. We deduce quantitative bounds on the merging time of the distributions for the chain started at two arbitrary points and we illustrate this new result with examples.
