c horizontal convexity on Carnot groupsmath.DG

Given a real-valued function cc defined on the cartesian product of a generic Carnot group $\G$ and the first layer V1V_1 of its Lie algebra, we introduce a notion of cc horizontal convex (cc H-convex) function on $\G$ as the supremum of a suitable family of affine functions; this family is defined pointwisely, and …
