چکیده
We give a closed formula for the dimension of all linear systems in Pn with assigned multiplicity at arbitrary collections points lying on rational normal curve degree n. In particular we purely geometric explanation speciality these systems, which is due to presence certain subvarieties base locus: spans points, secant varieties or joins between them.

Independence of Rational Points on Twists of a given Curve
In this paper, we study bounds for the number of rational points on twists C ′ of a fixed curve C over a number field K, under the condition that the group of K-rational points on the Jacobian J ′ of C ′ has rank smaller than the genus of C ′. The main result is that with some explicitly given finitely many possible exceptions, we have a bound of the form 2r + c, where r is the rank of J ′(K) a...

15 صفحه اولInflection points and singularities on planar rational cubic curve segments
We obtain the distribution of inflection points and singularities on a parametric rational cubic curve segment with aid of Mathematica (A System of for Doing Mathematics by Computer). The reciprocal numbers of the magnitudes of the end slopes determine the occurrence of inflection points and singularities on the segment. Its use enables us to check whether the segment has inflection points or a...
متن کاملLinear systems on a special rational surface
We study the Hilbert series of a family of ideals Jφ generated by powers of linear forms in K[x1, . . . , xn]. Using the results of Emsalem-Iarrobino, we formulate this as a question about fatpoints in P. In the three variable case this is equivalent to studying the dimension of a linear system on a blow up of P. The ideals that arise have the points in very special position, but because there ...
متن کاملOn the Saturation Sequence of the Rational Normal Curve
Let C ⊆ P denote the rational normal curve of order d. Its homogeneous defining ideal IC ⊆ Q[a0, . . . , ad] admits an SL2-stable filtration J2 ⊆ J4 ⊆ · · · ⊆ IC by sub-ideals such that the saturation of each J2q equals IC . Hence, one can associate to d a sequence of integers (α1, α2, . . . ) which encodes the degrees in which the successive inclusions in this filtration become trivial. In thi...
