Given a bounded domain and two integro-differential operators of the form we study the fully nonlinear Bellman equation
with Dirichlet boundary conditions. Here, are nonnegative functions. We prove the existence of a nonnegative function which satisfies (0.1) almost everywhere. The main difficulty arises through the nonlocality of and the absence of regularity near the boundary.
