The Orlik-Solomon algebra is the cohomology ring of the complement of the hyperplanes, either in complex projective or affine space. The optional Boolean argument
Projective specifies which. The code for this method was written by Sorin Popescu.
A = typeA(3) |
I = orlikSolomon(A,e) |
reduceHilbert hilbertSeries I |
I' = orlikSolomon(A,Projective=>true,HypAtInfinity=>2) |
reduceHilbert hilbertSeries I' |
The code for
orlikSolomon was contributed by Sorin Popescu.
