| Abstract: | The exponential convergence rate in entroy is studied for symmetric forms, with a special attention to the Markov chain with a state space having two points only. Some upper and lower bounds of the rate are obtained and five examples with precise or qualitatively exact estimates are presented. |
| Keywords: | Exponential convergence rate spectral gap logarithmic Sobolev constant symmetric form Markov chain |
