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…
