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
