An Empirically Fast Las Vegas Algorithm for Algebraic Shifting
Antony Della Vecchia, Michael Joswig, Fabian Lenzen
Improved algorithms for computing (partial and full) exterior algebraic shifts of hypergraphs and simplicial complexes are presented. The main benefit is in positive characteristic…
Partial Algebraic Shifting
Antony Della Vecchia, Michael Joswig, Fabian Lenzen
We study algebraic shifting of uniform hypergraphs and finite simplicial complexes in the exterior algebra with respect to matrices which are not necessarily generic. Several quest…
Subdivisions of Hypersimplices: with a View Toward Finite Metric Spaces
Laura Casabella, Michael Joswig, Lars Kastner
The secondary fan is a polyhedral fan which stratifies the regular subdivisions of the hypersimplices . We find new infinite families of rays of , and we c…
Computing convex hulls and counting integer points with polymake
Benjamin Assarf, Ewgenij Gawrilow, Katrin Herr +4
The main purpose of this paper is to report on the state of the art of computing integer hulls and their facets as well as counting lattice points in convex polytopes. Using the po…
