Phenomena, examples

This introductory Number Theory course will be accessible to first-year and second-year grad students with a modest background, and will proceed by extensive examples throughout, as motivation and explanation for more sophisticated methods and formalism.

I intend (by adapting the content to the population of students that show up!) that this course be interesting not only to students in Number Theory or Automorphic Forms, but also to students whose research areas interact frequently with these subjects, such as Algebraic Geometry, Mathematical Physics, Representation Theory, and Combinatorics, among others.

This course will give the phenomenological background to formalities such as the Langlands program, but I intend to take a broader approach.

Approximate/tentative outline:

[ background on complex analysis ]

  1. Classical GL(1) stories:
  2. Some classical GL(2) stories:
  3. Equidistribution example
  4. Classical L-functions for GL(2)
  5. Waveforms
  6. Pre-trace formulas and spectral theory of automorphic forms/functions
  7. Hilbert-Blumenthal modular forms
  8. Siegel modular forms
  9. Transition to GL2(A) and GLn(A)
  10. Theta lifts/correspondences, Segal-Shale-Weil representations:

This course introduces many phenomena that led to much contemporary research, including the Langlands program and much more. Little prior acquaintance with higher-level prerequisites is assumed. Rather, we will give examples that led to formation of many contemporary concepts and abstractions in number theory, complex analysis, Lie theory, harmonic analysis, representation theory, and algebraic geometry.

Units are listed in reverse chronological order. Notes will be linked-to as we go, somewhat in advance of progress in-class. If you must print notes, please don't do so until just before reading, because many updates will occur.

Our course will include much supporting material, beyond the strict topics of the title. Samples of other sources about modular forms themselves are below. Siegel's notes give number-theoretic applications of Hilbert modular forms.
