PL Morse theory in low dimensions
Romain Grunert, Wolfgang Kühnel, Günter Rote
We discuss a PL analogue of Morse theory for PL manifolds. There are several notions of regular and critical points. A point is homologically regular if the homology does not chang…

Combinatorial properties of the K3 surface: Simplicial blowups and slicings
Jonathan Spreer, Wolfgang Kühnel
The 4-dimensional abstract Kummer variety K^4 with 16 nodes leads to the K3 surface by resolving the 16 singularities. Here we present a simplicial realization of this minimal reso…

Hamiltonian submanifolds of regular polytopes
Felix Effenberger, Wolfgang Kühnel
We investigate polyhedral -manifolds as subcomplexes of the boundary complex of a regular polytope. We call such a subcomplex {\it -Hamiltonian} if it contains the full -…
