    In this paper, first, we propose two measures of inequality in multivariate distributions. One of these measures generalizes the Gini index to the multidimensional case. We study some properties of these two measures. We then introduce the notion of intrinsic inequality and inequality angle. Contrarily to the two defined inequality indexes, the intrinsic inequality will have the particularity to be similitude invariant. We give a geometric interpretation for it...
