The problem of computing a minimal set of generators for the ideal of a rational parametric projective curve has been tackled by elimination theory and can be solved by the computation of GrÃ¶bnerâ€¦ (More)

We present an implementation of an algorithm for computing minimal homogeneous generators and Hilbert functions of ideals of fat points. First we construct a set of generators by an interpolatingâ€¦ (More)

We pose a conjecture for the expected number of generators of the ideal of the union C of s general rational irreducible curves in P r. By using the computer we prove the conjecture for C of lowâ€¦ (More)

Let C be a projective algebraic curve. Suppose that C has ordinary singularities (with reduced tangent cones). In this paper we construct an efficient algorithm for computing locally, with polynomialâ€¦ (More)

The paper discusses over questions and hidden requests of andrological and sexological help in the general medical consultation of the elderly; the most frequent specific andrological symptoms andâ€¦ (More)

In 1982 Buchberger and MÃ¶ller described a polynomial algorithm to compute a reduced GrÃ¶bner basis of the ideal of affine points basing on interpolation methods. This algorithm was an incisive stepâ€¦ (More)

In this paper we extend the properties of ordinary points of curves [10] to ordinary closed points of one-dimensional affine reduced schemes and then to ordinary subvarieties of codimension one.

We extend results of our previous papers, on ordinary multiple points of curves [9], and on the computation of their conductor [8], to ordinary multiple subvarieties of codimension one.

The problem of determining an implicite representation of an irreducible algebraic variety given by a rational parametrization has been faced by elimination theory and can be solved by theâ€¦ (More)
