Abstract
Let A be the local ring, at a singular isolated point P of an affine irreducible algebraic variety V, with regular normalization. Let p be the prime ideal of A corresponding to V. In this paper we study the minimal number of generators of p, when the projectivized tangent cone of V at P is multilinear (that is union of linear varieties) and has maximal rankFile in questo prodotto:
