New characterizations of freeness for hyperplane arrangements
Anna Maria Bigatti, Elisa Palezzato, Michele Torielli
In this article we describe two new characterizations of freeness for hyperplane arrangements via the study of the generic initial ideal and of the sectional matrix of the Jacobian…

On the Falk invariant of signed graphic arrangements
Weili Guo, Michele Torielli
The fundamental group of the complement of a hyperplane arrangement in a complex vector space is an important topological invariant. The third rank of successive quotients in the l…

The minimal complex of supersolvable arrangements
Simona Settepanella, Michele Torielli
In this paper we give a very natural description of the bijections between the minimal CW-complex homotopy equivalent to the complement of a supersolvable arrangement …
