Tropical compactification via Ganter's algorithm
Lars Kastner, Kristin Shaw, Anna-Lena Winz
We describe a canonical compactification of a polyhedral complex in Euclidean space. When the recession cones of the polyhedral complex form a fan, the compactified polyhedral comp…
Immaculate line bundles on toric varieties
Klaus Altmann, Jarosław Buczyński, Lars Kastner +1
We call a sheaf on an algebraic variety immaculate if it lacks any cohomology including the zero-th one, that is, if the derived version of the global section functor vanishes. Suc…
Cellular sheaf cohomology in Polymake
Lars Kastner, Kristin Shaw, Anna-Lena Winz
This chapter provides a guide to our polymake extension cellularSheaves. We first define cellular sheaves on polyhedral complexes in Euclidean space, as well as cosheaves, and thei…
