The paper extends to an algebraic variety V of any dimension previous results of the authors for curves and algebraic surfaces. We compute the conductor of the local ring A of V at a singular isolated point with tangent cone consisting of a union of

Given a parametric polynomial representation of an algebraic Hypersurface S in the projective space we give a new algorithm for finding the implicit cartesian equation of S. The algorithm is based on finding a suitable finite number of points on S an

Let A be the local ring, at a singular point P, of an algebraic variety $$V\subset {\mathbb {A}}^{r+1}_k$$ of multiplicity $$e=e(A)>1$$. If V is a curve in Orecchia (Can Math Bull 24:423–431, 1981) P was said to be an ordinary singularity when V ha

Let $$A$$ be the local ring, at a singular isolated point $$P$$ of an affine irreducible algebraic variety $$V$$ , with regular normalization. Let $$\mathfrak p$$ be the prime ideal of $$A$$ corresponding to $$V$$ . In this paper we study the minimal
