摘要: |
本文主要研究环上的含参变量h的Boltzmann测度μh的对数Sobolev不等式.通过降维方法以及对该不等式最佳常数CLS(μh)的估计,证明了该测度关于h满足一致的对数Sobolev不等式,且对数Sobolev最佳常数CLS(μh)在h > 0时是具有常数阶的.结合已有的结果,再次佐证对数Sobolev不等式严格强于Talagrand传输不等式以及Poincaré不等式. |

Abstract: |
In this paper, we mainly study logarithmic Sobolev inequality on Boltzmann Measures with parameter h > 0 on circles. By the method of dimension-reduction and estimating the Log-Sobolev optimal constant, denoted by CLS(μh), we proved that the family of measures satisfy the uniform logarithmic Sobolev inequality in h and the optimal constant CLS(μh) has a constant order in h, which, together with the known results, enhances the claim that logarithmic Sobolev inequality is strictly stronger than Talagrand's transportation and Poincaré inequalities. |
