Before revision:  In particular, our approach through hedging strategy decomposition of the claim and its solution representation through system of nonlinear reflected BSDE (theorem 3.2.4) are the main contribution of the work.
After revision:  In particular, our approach through hedging strategy decomposition of the claim (proposition 2.2.5) and its price-hedge representation through system of nonlinear reflected BSDE (theorem 3.2.4) are the main contribution of the work.
