D.6.1.11 charexp2poly
Procedure from library alexpoly.lib (see alexpoly_lib).
- Assume:
- v an intvec containing the characterictic exponents of an irreducible plane curve singularity.
a a vector containing the coefficients of a parametrization given by x(t)=x^v[1],
y(t)=a(1)t^v[2]+...+a[n-1]t^v[n], i.e. the entries of a are of type number.
- Return:
- A polynomial f in the first two variables of the basering, such that f defines an
irreducible plane curve singularity with characteristic exponents v.
- Note:
- The entries in a should be of type number and the vector v should be the sequence of
characteristic exponents of an irreducible plane curve singularity in order to
get a sensible result,
