Instructor -- Pavel Guerzhoy

The class meets whenever the participants have questions to ask or discoveries to report

Usually, I respond to e-mail messages within a day. If I do not,that means that I do not have a reasonable answer, and am still thinking.
Office hours: Almost every afternoon, weekends included, whenever the participants have questions to ask or discoveries to report.

General Philosophy
This is a reading class with the objective to learn \(p\)-adic theories of modular forms.

It is supposed that students study the literature listed below during the semester. The reading should be smooth: questions should be immediately addressed to me, and discussed so that the student never gets stuck, and continues to study. The literature is organized and should be studied in a certain order.

This list will be updated in the course of semester.
Preparatory part
These texts are assumed to be well-known, and should only be consulted as handbooks. They contain all necessary definitions and principal theorems concerning the subjects involved.

    All in one, and more
    Lecture notes by Frank Calegari from an Arizona school are available on the web. These notes are devoted to the same target as our class. Assume, however, a more modest target: we want to become able to begin reading Calegari's text as a result of this class (and, probably, a class in algebraic geometry).

    Serre's theory
    should be learned from the original paper. This is easy to read piece of classics.

    Katz' theory
    is a bit more difficult since it requires some knowledge of mathematics. However, at least the statements of the theorems are accessible.

    \(p\)-adic families of modular forms
    Despite of the word "elementary" in the title, already the simplest approach to Hida's Control Theorem will seem to you neither elementary nor easy. However, the theorem itself is striking. That is Chapter 7 from
  • Hida, Haruzo; Elementary theory of L-functions and Eisenstein series. London Mathematical Society Student Texts, 26. Cambridge University Press, Cambridge, 1993. xii+386 pp. It is now natural to ask about what happens if the condition of being \(p\)-ordinary is relaxed. You will find a brief account of that (along with many things which you have already learned so far) in
  • Gouvêa, Fernando Q.; Arithmetic of p-adic modular forms. Lecture Notes in Mathematics, 1304. Springer-Verlag, Berlin, 1988. viii+121 pp. ISBN: 3-540-18946-7
