Viscosity solutions of fully nonlinear functional parabolic PDE

Blog Article

By the technique of coupled solutions, the notion of viscosity solutions is extended to fully nonlinear retarded parabolic equations.Such equations involve many T-Shirt models arising from optimal control theory, economy and finance, biology, and so forth.The comparison principle is shown.Then the existence and uniqueness read more are established by the fixed point theory.
