It is clear that Theorems 2.1–2.3 contain many combinatorial identities and we only list some of particular examples in Sects. But combinatorial identities where the sum is over all the partitions of a positive integer are rare. Jocelyn Quaintance. We shall prove Theorem 1.1 in Section 4, showing that McMullen’s [12] approach, which uses the incidence algebra of the face lattice, works also at the level of characteristic functions.
