VISCOSITY SOLUTIONS FOR CONTROLLED MCKEAN-VLASOV JUMP-DIFFUSIONS

摘要

We study a class of nonlinear integrodifferential equations on a subspace of all probability measures on the real line related to the optimal control of McKean-Vlasov jump-diffusions. We develop an intrinsic notion of viscosity solutions that does not rely on the lifting to a Hilbert space and prove a comparison theorem for these solutions. We also show that the value function is the unique viscosity solution.
