Combinatorial polar orderings and recursively orderable arrangements
Emanuele Delucchi, Simona Settepanella
Polar orderings arose in recent work of Salvetti and the second author on minimal CW-complexes for complexified hyperplane arrangements. We study the combinatorics of these orderin…

Combinatorial Morse theory and minimality of hyperplane arrangements
Mario Salvetti, Simona Settepanella
We find an explicit combinatorial gradient vector field on the well known complex S (Salvetti complex) which models the complement to an arrangement of complexified hyperplanes. Th…
