hyperplanes(Arrangement) -- the defining linear forms of an arrangement

Function: hyperplanes
Usage:

hyperplanes A

toList A
Inputs:
- A, a hyperplane arrangement,
Outputs:
- a list, the list of linear forms defining $A$.

Description

This returns the list of linear forms defining an arrangement. These forms will be elements of the coordinate ring of $A$.

i1 : A = typeA 3

o1 = {x  - x , x  - x , x  - x , x  - x , x  - x , x  - x }
