D.6.4.7 CharacteristicExponents
Procedure from library curvepar.lib (see curvepar_lib).
- Usage:
- CharacteristicExponents(i); i ideal
- Assume:
- i is the defining ideal of a (reducible) plane curve singularity.
- Return:
- list X of charts. Each chart contains the characteristic exponents
of the corresponding branch.
Example:
| LIB "curvepar.lib";
ring r=0,(x,y),ds;
ideal i=x14-x4y7-y11;
CharacteristicExponents(i);
