D.6.10.6 MultiplicitySequence
Procedure from library curvepar.lib (see curvepar_lib).
- Usage:
- MultiplicitySequence(i); i ideal
- Assume:
- i is the defining ideal of a (reducible) plane curve singularity.
- Return:
- list X of charts. Each chart contains the multiplicity sequence of
the corresponding branch.
Example:
| LIB "curvepar.lib";
ring r=0,(x,y),ds;
ideal i=x14-x4y7-y11;
MultiplicitySequence(i);
==> [1]:
==> 1
==> [2]:
==> 1
==> [3]:
==> 1
==> [4]:
==> 1
==> [5]:
==> 7,3,3,1,1,1
