On the intersection of contingent cones

  • V. Křivan
Technical Note


In this paper, we give a new condition that ensures the equalityT K (x) ∩T L (x)=T K ∩ L (x) for convex closed setsK,L. This condition, which is given in terms of support functions of the setsK,L, generalizes, in a Hilbert space, the usual condition 0εint(KL).

Key Words
