We prove the existence and uniqueness of the L$$-variational solution, with p > 1, of the following multivalued backward stochastic differential equation with p-integrable data:
| $$ |
where τ is a stopping time, Q is a progressively measurable increasing continuous stochastic process and ∂$$Ψ is the subdifferential of the convex lower semicontinuous function y↦Ψ(t, y). In the framework of [14] (the case p ≥ 2), the strong solution found it there is the unique variational solution, via the uniqueness property proved in the present article.
Keywords: Backward stochastic differential equations, subdifferential operators, Stochastic variational inequalities, $$-integrable data
