D.5.5.18 multiplicities
Procedure from library hnoether.lib (see hnoether_lib).
- Usage:
- multiplicities(L); L list
- Assume:
- L is the output of
develop(f) , or of
extdevelop(develop(f),n) , or one entry of the output of
reddevelop(f) .
- Return:
- intvec of the different multiplicities that occur when successively
blowing-up the curve singularity corresponding to f.
Example:
| LIB "hnoether.lib";
int p=printlevel; printlevel=-1;
ring r=0,(x,y),dp;
multiplicities(develop(x5+y7));
==> 5,2,1
// The first value is the multiplicity of the curve itself, here it's 5
printlevel=p;
