Balanced squeezed Complexes

Martina Juhnke-Kubitzke, Uwe Nagel

Given any order ideal consisting of color-squarefree monomials involving variables with colors, we associate to it a balanced -dimensional simplicial complex $Δ_{\ma…

Squeezed Complexes

Martina Juhnke-Kubitzke, Uwe Nagel

Given a shifted order ideal , we associate to it a family of simplicial complexes that we call squeezed complexes. In a special case, our construction gives…

Signed lozenge tilings

David Cook, Uwe Nagel

It is well-known that plane partitions, lozenge tilings of a hexagon, perfect matchings on a honeycomb graph, and families of non-intersecting lattice paths in a hexagon are all in…

Enumerations of lozenge tilings, lattice paths, and perfect matchings and the weak Lefschetz property

David Cook, Uwe Nagel

MacMahon enumerated the plane partitions in an box. These are in bijection to lozenge tilings of a hexagon, to certain perfect matchings, and to families of n…

Cohen-Macaulay graphs and face vectors of flag complexes

David Cook, Uwe Nagel

We introduce a construction on a flag complex that, by means of modifying the associated graph, generates a new flag complex whose -factor is the face vector of the original com…

On the shape of a pure O-sequence

M. Boij, J. Migliore, R. Miro'-Roig +2

An order ideal is a finite poset X of (monic) monomials such that, whenever M is in X and N divides M, then N is in X. If all, say t, maximal monomials of X have the same degree, t…
