I consider an n-dimensional generalized metric space Sn with coordinates xi(h, i, j, k… run from 1 to n throughout), with each point of which is associated a contravariant vector-density with components ui and weight p, called the element of support. The unit vector in the direction of the element of support has components denoted by li.
