%0 Journal Article %T A probabilistic approach to Dirichlet problems of semilinear elliptic PDEs with singular coefficients %A Tusheng Zhang %J Mathematics %D 2012 %I arXiv %R 10.1214/10-AOP591 %X In this paper, we prove that there exists a unique solution to the Dirichlet boundary value problem for a general class of semilinear second order elliptic partial differential equations. Our approach is probabilistic. The theory of Dirichlet processes and backward stochastic differential equations play a crucial role. %U http://arxiv.org/abs/1211.3820v1
