In [11] it is proved that length-minimizing curves in Carnot groups have infinitesimal excess at any point, for a suitable sequence of scales. In this paper we prove some results dealing with the small excess regime. We prove a height-estimate for horizontal curves and an approximation of geodesics with Lipschitz graphs along the direction where excess is small. The setting is that of free Carnot groups.

Abstract
In [11] it is proved that length-minimizing curves in Carnot groups have infinitesimal excess at any point, for a suitable sequence of scales. In this paper we prove some results dealing with the small excess regime. We prove a height-estimate for horizontal curves and an approximation of geodesics with Lipschitz graphs along the direction where excess is small. The setting is that of free Carnot groups.File in questo prodotto:
