On the k-Systems of a Simple Polytope
Michael Joswig, Volker Kaibel, Friederike K"orner
A k-system of the graph G(P) of a simple polytope P is a set of induced subgraphs of G(P) that shares certain properties with the set of subgraphs induced by the k-faces of P. This…
Discrete Morse Complexes
Manoj K. Chari, Michael Joswig
We investigate properties of the set of discrete Morse functions on a simplicial complex as defined by Forman. It is not difficult to see that the pairings of discrete Morse functi…
Vertex-Facet Incidences of Unbounded Polyhedra
Michael Joswig, Volker Kaibel, Marc E. Pfetsch +1
How much of the combinatorial structure of a pointed polyhedron is contained in its vertex-facet incidences? Not too much, in general, as we demonstrate by examples. However, one c…
