D.15.33.27 contributionBundle

Procedure from library schubert.lib (see schubert_lib).

Usage:
contributionBundle(M,G,#); M stack, G graph, # list

Return:
number

Input:
M is a moduli space of stable maps, G is a graph, # is a list.

Output:
a number corresponding to the contribution bundle on a moduli space of stable maps at a fixed point component (graph)

Example:
 
LIB "schubert.lib";
ring r = 0,x,dp;
variety P = projectiveSpace(4);
stack M = moduliSpace(P,2);
def F = fixedPoints(M);
graph G = F[1][1];
number f = contributionBundle(M,G);
number g = contributionBundle(M,G,5);
f == g;
==> 1
