D.5.17.26 fixedPoints
Procedure from library schubert.lib (see schubert_lib).
- Usage:
- fixedPoints(M); M stack
- Return:
- list
- Input:
- M is a moduli space of stable maps.
- Output:
- a list of graphs corresponding the fixed point components of a torus
action on a moduli space of stable maps.
Example:
| LIB "schubert.lib";
ring r = 0,x,dp;
variety P = projectiveSpace(4);
stack M = moduliSpace(P,2);
def F = fixedPoints(M);
size(F);
==> 100
typeof(F[1]) == "list";
==> 1
typeof(F[1][1]) == "graph";
==> 1
typeof(F[1][2]) == "int";
==> 1
