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

โฆ Synopsis
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 apply our results to the global case.

For an algebraic curve CรK defined by y 2 =x p +a (a ร K p ) with relative genus ( p&1)ร2 and absolute genus 0, we prove that the Picard group of divisors of degree 0, denoted Pic 0 K (C), of a curve CรK fixed by the action of the Galois group G= gal(K sep รK) has a finite number of K-rational point
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 Functi
Consider a curve of genus one over a field K in one of three explicit forms: a double cover of P 1 , a plane cubic, or a space quartic. For each form, a certain syzygy from classical invariant theory gives the curve's jacobian in Weierstrass form and the covering map to its jacobian induced by the K
A function F (x, y, t) that assigns to each parameter t an algebraic curve F (x, y, t) = 0 is called a moving curve. A moving curve F (x, y, t) is said to follow a rational curve x = x(t)/w(t), y = y(t)/w(t) if F (x(t)/w(t), y(t)/w(t), t) is identically zero. A new technique for finding the implici
