Abstract
The convergence to stationarity of many finite ergodic Markov chains presents a sharp cut-off: there is a time T such that before time T the chain is far from its equilibrium and, after time T, equilibrium is essentially reached. We will discuss precise definitions of the cut-off phenomenon, examples, and some partial results and conjectures.
