Max Noether's theorem on curves

In algebraic geometry, Max Noether's theorem on curves is a theorem about curves lying on algebraic surfaces, which are hypersurfaces in P3, or more generally complete intersections. It states that, for degree at least four for hypersurfaces, the generic such surface has no curve on it apart from the hyperplane section. In more modern language, the Picard group is infinite cyclic, other than for a short list of degrees. This is now often called the Noether-Lefschetz theorem. * v * t * e (Wikipedia).

Weil conjectures 1 Introduction

This talk is the first of a series of talks on the Weil conejctures. We recall properties of the Riemann zeta function, and describe how Artin used these to motivate the definition of the zeta function of a curve over a finite field. We then describe Weil's generalization of this to varie

Riemann Roch: plane curves

This talk is about some properties of plane curves used in the Riemann-Roch theorem. We first show that every nonsingular curve is isomorphic to a resolution of a plane curve with no singularities worse than ordinary double points (nodes). We then calculate the genus of plane curves with o

Hannah Larson - A refined Brill-Noether theory over Hurwitz spaces - AGONIZE miniconference

The celebrated Brill-Noether theorem says that the space of degree d maps of a general genus g curve to ℙr is irreducible. However, for special curves, this need not be the case. Indeed, for general k-gonal curves (degree k covers of ℙ1), this space of maps can have many components, of dif

Abstract: The classical Brauer-Siegel theorem can be seen as one of the first instances of description of asymptotical arithmetic: it states that, for a family of number fields Ki, under mild conditions (e.g. bounded degree), the product of the regulator by the class number behaves asympt

Weil conjectures 3: Riemann hypothesis

This talk is about the Stepanov-Bombieri proof of the Riemann hypothesis for curves over a finite field. The proof works by finding a nonzero function that vanishes to high order at all points of the curve defined over the finite field Fq, and has a single pole of known order. The proof is
