Abstract:
The Arakelov class group of a number field is analogous to the Picard group of a curve. Instead of line bundles, it classifies ideal lattices. In these lectures we explain this analogy and pay special attention to computational aspects.
René Schoof's Short Bio:
René Schoof received his PhD from the University of Amsterdam. He is a professor at Università di Roma "Tor Vergata" in Rome, Italy. His research interests include Algebraic Number Theory, Arakelov Theory, Iwasawa Theory, Computational Number Theory and Abelian Varieties. He invented the first polynomial-time algorithm for counting points on elliptic curves over finite fields, which has major applications in number theory and cryptography. He wrote a book on Mihailescu's proof of the Catalan's conjecture.
