主 题:Reflected backward stochastic differential equation g-expectation Optional barrier Monotone approximation Comparison principle
摘 要:In this short note we consider reflected backward stochastic differential equations(RBSDEs)with a Lipschitz driver and barrier processes that are optional and right lower *** this case,the barrier is represented as a nondecreasing limit of right continuous with left limit(RCLL)*** combine some well-known existence results for RCLL barriers with comparison arguments for the control process to construct ***,we highlight the connection of these RBSDEs with standard RCLL BSDEs.
