This package contains two types for working with divisor classes and curve classes on $\bar{M}_{0,n}$, the moduli space of stable n-pointed genus zero curves. The basic types are DivisorClassRepresentativeM0nbar and CurveClassRepresentativeM0nbar.

i2 : C=curveClassRepresentativeM0nbar(5,L1); |
i3 : L2=new HashTable from { {{1,3},1}, {{1,4},1}}; |
i4 : D=divisorClassRepresentativeM0nbar(5,L2); |
i5 : intersection(C,D) o5 = 6 |
