Abstract: We compute the set of all extreme rays of the 6-party subadditivity cone that are compatible with strong subadditivity. In total, we identify 208 new (genuine 6-party) orbits, 52 of which violate at least one… read more here.

DOI: 10.1057/s41274-017-0265-9
Abstract: This paper presents a new method which can be used in two different situations: Firstly, for converting certain polyhedral cones of intersection form to cones of sum form, this method identifies all the extreme rays… read more here.
