D.6.3.8 arnoldMilnorCode
Procedure from library arnoldclassify.lib (see arnoldclassify_lib).
- Usage:
- arnoldMilnorCode(f[,e]); f poly, e int
- Assume:
- basering is local, f has isolated critical point at 0
- Compute:
- Milnor code of f consisting of the numbers of successive repetitions
of coefficients of the 2nd Hilbert series of basering/(jacob(f)^e),
see [Bac01].
- Return:
- Milnor code of f as intvec where e=1 by default
Example:
| | LIB "arnoldclassify.lib";
ring r=0,(x,y,z),ds;
poly f=x2y+y3+z2;
arnoldMilnorCode(f);
==> 1,1,1
arnoldMilnorCode(f,2);
==> 1,1,2,1
// a big second argument may result in memory overflow
