Comparison principles for subelliptic equations of Monge-Ampère type
نویسندگان
چکیده
We present two comparison principles for viscosity suband supersolutions of Monge-Ampère-type equations associated to a family of vector fields. In particular, we obtain the uniqueness of a viscosity solution to the Dirichlet problem for the equation of prescribed horizontal Gauss curvature in a Carnot group.

Regularity of Subelliptic Monge-ampère Equations in the Plane
We establish a C∞ regularity result for C1,1 solutions of degenerate Monge-Ampère equation in R2, under the assumption that the trace of the Hessian is bounded from below.

We study fully nonlinear partial differential equations involving the determinant of the Hessian matrix of the unknown function with respect to a family of vector fields that generate a Carnot group. We prove a comparison theorem among viscosity suband supersolutions, for subsolutions uniformly convex with respect to the vector fields.

We study partial differential equations of Monge-Ampère type involving the derivates with respect to a family X of vector fields of Carnot type. The main result is a comparison principle among viscosity subsolutions, convex with respect to X , and viscosity supersolutions (in a weaker sense than usual), which implies the uniqueness of solution to the Dirichlet problem. Its assumptions include t...
