A generalization of Poletsky's classical theorem and a characterization   of thinness of a subset in $\C^n$
  In this paper we generalize Poletsky's classical theorem to a situation where the kernel of Poisson functional is not upper semicontinuous. We give a characterization of thinness of a subset at a point in $\C^n$ in term of analytic discs.
