Abstract.
We define the extremal length of horizontal vector measures on a Carnot group and study capacities associated with linear subelliptic equations. The coincidence between the definition of the $p$module of horizontal vector measure system and two different definitions of the $p$capacity is proved. We show the continuity property of a $p$module generated by a family of horizontal vector measures. Reciprocal relations between the $p$capacity and $q$module $(1/p+1/q=1)$ of horizontal vector measures are obtained. A peculiarity of our approach consists of the study of the above mentioned notions in domains with an intrinsic metric.
