M0nbar -- calculations for divisors and curves on the moduli space of stable n-pointed genus zero curves

Description

This package contains two types for working with divisor classes and curve classes on M0,n, the moduli space of stable n-pointed genus zero curves. The basic types are DivisorClassRepresentativeM0nbar and CurveClassRepresentativeM0nbar.

i1 : L1= { {{{2,1},{3},{4},{5}},-2}, {{{1,3},{2},{4},{5}},-7}, {{{1,4},{2},{3},{5}},1}};
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)
