RT Book, Section T1 On the k-additive Core of Capacities A1 Grabisch, Michel A1 Miranda Menéndez, Pedro A2 Stepnicka, Martin A2 Novák, Vilém A2 Bodenhofer, Ulrich AB We investigate in this paper the set of k-additive capacities dominating a given capacity,which we call the k-additive core. We study its structure through achievable families, which play the role of maximal chains in the classical case (k = 1), and show thatassociated capacities are elements (possibly a vertex) of the k-additive core when the capacity is (k+1)-monotone. As a particular case, we study the set of k-additive belief functions dominating a belief function. The problem of finding all vertices of the k-additive core is still an open question.
