Reflected backward stochastic differential equations with jumps and partial integro-differential variational inequalities.

Summary We study the links between reflected backward stochastic differential equations (reflected BSDEs) with jumps and partial integro-differential variational inequalities (PIDVIs). In a Markovian framework, we show that the solution of the reflected BSDE corresponds to the unique viscosity solution of the PIDVI. We apply these results to an optimal stopping problem for dynamic risk measures induced by BSDEs with jumps.
