Level Eulerian Posets
Richard Ehrenborg, Gábor Hetyei, Margaret Readdy
The notion of level posets is introduced. This class of infinite posets has the property that between every two adjacent ranks the same bipartite graph occurs. When the adjacency m…

The short toric polynomial
Gábor Hetyei
We introduce the short toric polynomial associated to a graded Eulerian poset. This polynomial contains the same information as the two toric polynomials introduced by Stanley, but…

A second look at the toric h-polynomial of a cubical complex
Gábor Hetyei
We provide an explicit formula for the toric -contribution of each cubical shelling component, and a new combinatorial model to prove Clara Chan's result on the non-negativity o…
