English abstract:
Discrete Beckner inequalities, which interpolate between the modified loga-rithmic Sobolev inequality and the Poincare´ inequality, are derived for time-continuous Markov chains on countable state spaces. The proof is based on the Bakry-Emery ap-proach and on discrete Bochner-type inequalities established by Caputo, Dai Pra, and Posta and recently extended by Fathi and Maas. The abstract result is applied to several Markov chains, including birth-death processes, zero-range processes, Bernoulli-Laplace models, and random transportation models, and to a finite-volume discretization of a one-dimensional Fokker-Planck equation, applying results by Mielke.
