On an explicit correspondence between nbc-basis, chambers and minimal complex for real supersolvable arrangements

On an explicit correspondence between nbc-basis, chambers and minimal complex for real supersolvable arrangements
In this paper we give a very natural description of the bijections between the set of cells in the minimal CW-complex homotopy equivalent to the complement of a complexified real supersolvable arrangement A, the nbc-basis of the Orlik-Solomon algebra associated to A and the set of chambers of A.

On the Finite Group Which Is a Product of Two Subnormal Supersolvable Subgroups

Mathematics, 2022
Let G be a finite group that is a product of two subnormal ( normal) supersolvable subgroups. The following are interesting topics in the study of the structure of G: obtaining the conditions in addition to guarantee that G is supersolvable and giving ...

Lattice and order properties of the poset of regions in a hyperplane arrangement [PDF]

Algebra Universalis, 2003
We show that the poset of regions (with respect to a canonical base region)of a supersolvable hyperplane arrangement is a congruence normal lattice. Specifically,the poset of regions of a supersolvable arrangement of rank k is obtained via a sequenceof ...
