Remarks on non-interacting conservative spin systems: The case of gamma distributions

Stochastic Processes and their Applications, 2009, vol. 119, issue 8, 2711-2723

Abstract: We provide precise estimates of the spectral gap and logarithmic Sobolev constants of canonical Gibbs measures associated to gamma distributions with parameter [alpha]>=1. This is related to the Kannan-Lovász-Simonovits conjecture for simplices and unit balls of spaces.
