Nuclei of Normal Rational Curves

A k–nucleus of a normal rational curve in PG(n, F ) is the intersection over all k–dimensional osculating subspaces of the curve (k ∈ {−1, 0, . . . , n− 1}). It is well known that for characteristic zero all nuclei are empty. In case of characteristic p > 0 and #F ≥ n the number of non–zero digits in the representation of n+ 1 in base p equals the number of distinct nuclei. An explicit formula ...

Completeness of Normal Rational Curves

The completeness of normal rational curves, considered as (q + 1)-arcs in PG(n, q), is investigated. Previous results of Storme and Thas are improved by using a result by Kovacs. This solves the problem completely for large prime numbers q and odd nonsquare prime powers q = p2h+l with p prime, p > po(h), h>\,1where po(h) is an odd prime number which depends on h.

Dynamical systems for rational normal curves

We construct dynamical systems with Pn as state space, using (n+1)×(n+1) matrices of linear forms in n+1 variables, such that the fixed point sets are rational normal curves minus one point. Our matrices provide canonical forms for the triple action of PGLn+1 on the projective space of such matrices. Our dynamical systems include parameters identified with points in Pn−1. We find conditions on ...

Deciding Existence of Rational Points on Curves: An Experiment

The problem to decide whether a given algebraic variety defined over the rational numbers has rational points is fundamental in Arithmetic Geometry. Abstracting from concrete examples, this leads to the question whether there exists an algorithm that is able to perform this task for any given variety. This is probably too much to ask for: we know that Hilbert’s Tenth Problem, which asks the sam...
