On minimal conies

This paper contains tow new results about minimal sets in euclidean spaces. The first one is of the Maximum principle type, and proves that if C1⊂C2 are minimal singular cones, then C1= C2 This result completes those proven in16 and 17. The second result proves that in every singular minimal cone , a nonempty minimal set E is strictly contained. If C is the “smallest” singular minimal cone in its dimension, then the boundary of E is analytic
