Singular Manual: normalBundle

| #### D.5.17.28 normalBundle Procedure from library `schubert.lib` (see schubert_lib). Return: number Input: M is a moduli space of stable maps, G is a graph Output: a number corresponding to the normal bundle on a moduli space of stable maps at a graph hypersurfaces 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 = normalBundle(M,G);
    f <> 0;
    ==> 1
