Query: Variational formulas for the exit time of Hunt processes generated by
  semi-Dirichlet forms   Variational formulas for the Laplace transform of the exit time from an open
set of a Hunt process generated by a regular lower bounded semi-Dirichlet form
are established. While for symmetric Markov processes, variational formulas are
derived for the exponential moments of the exit time. As applications, we
provide some comparison theorems and quantitative relations of the exponential
moments and Poincar\'e inequalities.
