We give a dual representation of minimal supersolutions of BSDEs with non-bounded, but integrable terminal conditions and under weak requirements on the generator which is allowed to depend on the value process of the equation. Conversely, we show that any dynamic risk measure satisfying such a dual representation stems from a BSDE. We also give a condition under which a supersolution of a BSDE is even a solution. 
Minimal supersolutions of convex BSDEs under constraints
We study supersolutions of a backward stochastic differential equation, the control processes of which are constrained to be continuous semimartingales of the form d Z = Δ d t + Γ d W . The generatorExpand

A new methodology for the construction of time-consistent dynamic risk measures is introduced, starting with right-continuous BMO martingales, and this construction naturally leads to paths with jumps. Expand
