Lecture notes: Tentative lecture notes:
Notes (pdf file, a tentative version).

Grading will be based on student presentation at the end of courses on topics close to the course material. No final exam is planned.

As reference books, we suggest

  • T. Miyake, "Modular Forms", Springer Monograph of Mathematics, New York-Tokyo, 2006,
  • H. Hida, "Elementary Theory of L-functions and Eisenstein Series", LMSST 26, Cambridge University Press, Cambridge, 1993,
  • H. Hida, "Geometric Modular Forms and Elliptic Curves", Second Expanded Edition, World Scientific Publishing Co., Singapore, 2011,
  • Topics: In this course, assuming basic knowledge of complex analysis, we describe basics of elliptic modular forms. We hope to cover the following four topics:

  • Galois deformation theory,
  • Hecke algebra as deformation rings,
  • Integrality of adjoint L-values,
  • Congruence among cusp forms and a non-abelian class number formula.
  • Prerequisite:
    Good understanding of commutative and non-commutative algebra, complex analysis (for Riemann surfaces) and algebraic number theory.
