β¦ Synopsis
In this paper we study 0-dimensional schemes Z made of "fat points" in pn, n > 2, whose support lies on a rational normal curve. We conjecture that the Hilbert function of Z does not depend on the choice of the points and we show this under some numerical hypotheses. We also study the Hilbert Function of the infinitesimal neighborhoods of the rational normal curve and we find the value where it coincides with the Hilbert Polynomial.

Let K be an algebraic function field in one variable over an algebraically closed field of positive characteristic p. We give an explicit upper bound for the number of rational points of genus-changing curves over K defined by y p =r(x) and show that every genus-changing curve of absolute genus 0 ha
Tate proved a theorem on rational points of torsors ("Torsors" means "Homogeneous spaces," in sequel we use "torsors" in this meaning) of \(T / K\), where \(K\) is a local field, \(T\) is a Tate curve. In this paper we extend the above theorem to the case where \(T\) is a twist of a Tate curve, and
