摘要
Some variational formulas for the exit time and asymptotic variance for a Hunt process generated by a regular lower bounded semi-Dirichlet form are established. While for symmetric cases, variational formulas are derived for the exponential moments of the exit time.
As applications, we provide some comparison theorems for exit time and asymptotic variance, and present the Polya-type inequalities which describe quantitative relations of the exponential/polynomial moments and Poincare inequalities.
