Supersolvable arrangement

In mathematics, a supersolvable arrangement is a hyperplane arrangement which has a maximal flag with only modular elements.

Examples include arrangements associated with Coxeter groups of type A and B.

It is known that all Orlik–Solomon algebras of supersoluble arrangements are Koszul algebras.[1]
