Riemann–Roch theorem Wikipedia. The Riemann Roch theorem for compact Riemann surfaces was proved by Riemann and Roch in the 1850s. It connects the complex analysis of a compact Riemann surface with its purely topological property, viz genus in a purely algebraic setting. It has numerous applications in, the courses of modular forms, abelian varieties and complex multiplication). Chapter 1 gives a brief overview on the algebraic geometry results and tools we will need along the whole thesis. Chapter 2 introduces and develops the theory of elliptic curves, firstly as an algebraic curve over a generic field, and then focusing on the fields of complex and rational numbers, in particular for the.

riemann roch theorem application to modular forms

The classical Riemann-Roch theorem is a fundamental result in complex analysis and algebraic geometry. In its original form, developed by Bernhard Riemann and his student Gustav Roch in the mid-19th century, the theorem provided a connection between the analytic and topological properties of compact Riemann surfaces. This connection arises from Riemann-Roch theorem for arbitrary projective morphisms of regular arithmetic varieties. As an application, we compute the main characteristic numbers of the homogenous theory, a question that was left open in [9]. Acknowledgements. We would like to thank the following institutions where part

nt.number theory Why are modular forms interesting. As Benjamin mentions, Serre duality plays a key role in understanding the meat of Riemann-Roch for curves. However, there are more general forms of Riemann-Roch, all of which can somehow be understood as the "equality" $$\text{topological data} = \text{algebraic data}.$$ In the case of curves, this is straightforward. By rewriting the Riemann, Motivation. Originellement, il répond au problème de la recherche de l'existence de fonctions méromorphes sur une surface de Riemann donnée, sous la contrainte de ….

In mathematics, the Hodge bundle, named after W. V. D. Hodge, appears in the study of families of curves, where it provides an invariant in the moduli theory of algebraic curves. Furthermore, it has applications to the theory of modular forms on reductive algebraic groups and string theory. of the major results that I will use to prove the Riemann-Roch theorem. Equipped with our armamentarium of mathematical tools, I will present the Riemann-Roch theorem in its entirety followed by some of its many applications to algebraic geometry. 1
