Abstract: | In this paper we develop a new weak convergence and compact embedding method to study the existence and uniqueness of the
Lr2p(\mathbbRd;\mathbbR1)×Lr2(\mathbbRd;\mathbbRd)L_{\rho}^{2p}({\mathbb{R}^{d}};{\mathbb{R}^{1}})\times L_{\rho}^{2}({\mathbb{R}^{d}};{\mathbb{R}^{d}}) valued solution of backward stochastic differential equations with p-growth coefficients. Then we establish the probabilistic representation of the weak solution of PDEs with p-growth coefficients via corresponding BSDEs. |
