It is very interesting to study what problems can be computed in irreducible plane curve singularities in algebraicgeometry? Then, the aim of this talk is to compute the explicit algorithm for finding the correspondence between the family of irreducible Weierstrass polynomials, the family of the Puiseux expansions, the family of multiplicity sequences and the family of the divisors defined by irreducible plane curve singularities under the standard resolutions.
