Abstract
The equality case in the general quadratic inequality V(K, L, K 1, ..., K n−2)2 ≥ V(K, K, K 1, ..., K n−2) V(L, L, K 1, ..., K n−2) for mixed volumes is settled under the assumption that K and L are centrally symmetric and K 1, ..., K n−2 are zonoids. This result partly confirms a conjecture on the general case made in an earlier paper.
