Graduate mini-course on the Birch and Swinnerton-Dyer conjecture
Lecturers: Henri Darmon and
Dates: Monday, September 8 to Thursday, September 18, 2014.
Location: The Steklov Institute, Moscow.
The goal of the mini course shall be to discuss the Birch and Swinnerton
Dyer (BSD) conjecture. One of the most celebrated open problems in number
theory, it is among the Clay Institute's seven "millenium prize problems".
Attempts to better understand and generalise it form the basis for some
of the most fundamental advances in the subject over the last five decades.
Since its formulation in the early 60's, progress on the BSD conjecture
has come principally from the following directions:
1. The seminal work of Coates and Wiles in the late 70's which established the
very first cases of the conjecture, for elliptic curves
with complex multiplication and analytic rank 0.
2. The combined breakthrough by Gross-Zagier and Kolyvagin in the 1980's, which leads to a
proof of the BSD conjecture for all (modular)
elliptic curves over Q of analytic rank 0
or 1; this approach also gives strong information about their
Mordell-Weil and Shafarevich Tate groups
over ring class fields of imaginary quadratic fields.
3. The work of Kato in the 1990's
establishing the BSD conjecture in analytic rank zero, for
elliptic curves over Q and their
groups over cyclotomic fields.
4. The more recent complementary approach
of Skinner and Urban from the last decade
which, inspired from earlier work of Mazur and Wiles on the arithmetic
of cyclotomic fields, has led to a proof of the Birch and Swinnerton-Dyer
conjecture for all modular elliptic curves of algebraic
rank 0, as well as a proof of the
"main conjecture" of Iwasawa theory in this context.
After presenting a broad outline of these approaches, with emphasis on their fundamental similarities
and differences, the course will be devoted to recent progress
on the Birch and Swinnerton-Dyer conjecture
for Mordell-Weil groups over ring class fields of real quadratic fields.
Eventual connections with the theory of Stark-Heegner points and the problem
of "explicit class field theory" for real quadratic fields will be addressed.
The course will assume basic background in the arithmetic of elliptic curves, such as might be covered in
volume I of Silverman's book, as well as some background on modular forms and their
connection with elliptic curves via the Shimura Taniyama conjecture. An excellent reference for this material
is the textbook by Diamond and Shurman. A terse synopsis of the required material can also be found in the first
three chapters of the book
Rational points on modular elliptic curves,

Chapter 10 also cover more specialised, but very relevant, material on the method of Kolyvagin, and Chapters 8 and 9
give a brief and somewhat outdated account of the theory of Stark-Heegner points. Better references for these two topics
are, respectively, Gross's article on Kolyvagin's method which appeared in the Proceedings of the Durham Symposium in 1989,
and the article of Matthew Greenberg that appears in the Duke Math Journal (vol 147) in 2009.
