The enumerator function F(PB) of positive lattice points in interiors of maximal cones of the normal fan of the nestohedron PB associated to a building set B is described as a morphism from the certain combinatorial Hopf algebra of building sets to quasisymmetric functions. We define the q-analog Fq(PB) and derive its determining recurrence relations. The f -polynomial of the nestohedron PB appears as the principal specialization of the quasisymmetric function Fq(PB). |
