Keywords: | Combinatorial Hopf algebra;f-polynomial;Generalized permutohedron;Quasisymmetric function | Issue Date: | 2020 | Journal: | Journal of Algebraic Combinatorics | Abstract: | We introduce a weighted quasisymmetric enumerator function associated with generalized permutohedra. It refines the Billera, Jia and Reiner quasisymmetric function which also includes the Stanley chromatic symmetric function. Besides that, it carries information of face numbers of generalized permutohedra. We consider more systematically the cases of nestohedra and matroid base polytopes. |
