Equivariant incidence algebras and equivariant Kazhdan–Lusztig–Stanley theory
Nicholas Proudfoot
Source abstract
We establish a formalism for working with incidence algebras of posets with symmetries, and we develop equivariant Kazhdan–Lusztig–Stanley theory within this formalism. This gives a new way of thinking about the equivariant Kazhdan–Lusztig polynomial and equivariant Z -polynomial of a matroid.
