Instructional Conference, May 7-11, 2007, Lorentz Center.

Back to the website of the instructional conference  |  Prerequisites  |  Hand-outs and exercises


The lectures are in Room 201 on the second floor and the social activities in the Common room on the third floor. On Monday-Thursday mornings there are lectures. In the afternoons there are exercise sessions where the participants can practice with the theory discussed in the morning lectures. On Friday there will be a series of lectures meant for a general audience.

Algebraic number theory:
Ideals, unit groups, S-unit groups, class groups, completions, p-adic valuations, p-adic analysis.

S. Lang, Algebraic Number Theory, Chapters 1,2,7 or
J. Neukirch, Algebraic Number Theory, Chapters 1,2

More about p-adic analysis (basics about p-adic power series):
Z.I Borevich, I.R. Shafarevich, Number Theory, Chapter 4

Algebraic curves and elliptic curves:
Function fields, divisors, Picard group, differentials, basic facts about elliptic curves and reduction modulo p of an elliptic curve (vague idea of how this works). Part of this will be recalled briefly during the course.

J.H. Silverman, The arithmetic of elliptic curves,
Chapters 1,2,
Chapter 3 sections 1,2,3; sections 4,5 will be useful,
Chapter 7, sections 1,2; sections 3,4,5 will be useful.

Recommended for further reading:
p-adic methods and some facts about genus 2 curves (not required but useful)
