This program is intended for Ph.D students and postdocs interested in working in algebraic number theory. Some M.Sc students may also be able to attend depending on their background. The background required for this workshop includes basic algebraic number theory, commutative algebra, field theory and Galois theory, representation theory. There will be some preparatory lectures covering Herbrand-Ribet theorem, basic Iwasawa theory, p-adic L-functions. Along with that, the program will have lectures on the following topics: ordinary Λ-adic modular forms, Λ-adic Galois representations, proof of Iwasawa main conjecture.
