D.6.1.7 charexp2multseq
Procedure from library alexpoly.lib (see alexpoly_lib).
- Usage:
- charexp2multseq(v), v intvec
- Assume:
- v contains the characteristic exponents of an irreducible plane
curve singularity
- Return:
- intvec, the multiplicity sequence of the plane curve singularity
- Note:
- If the curve singularity is smooth, then the multiplicity sequence is empty.
This is expressed by returning zero.
Example:
| | LIB "alexpoly.lib";
charexp2multseq(intvec(28,64,66,77));
==> 28,28,8,8,8,4,4,2,2,2,2,2,2,2,1,1
