This is a master course given in Moscow at the Laboratory of Algebraic Geometry of the National Research University Higher School of Economics by Valery Gritsenko, a professor of University Lille 1, France.
Jacobi forms are holomorphic functions in two complex variables. They are modular in one variable and abelian (or double periodic) in another variable. The theory of Jacobi modular forms became an independent research subject after the famous book of Martin Eichler and Don Zagier “Jacobi modular forms” (Progress in Mathematics, vol. 55, 1985) which was cited more than a thousand times in research papers. This is due to many applications of Jacobi forms in arithmetic, topology, algebraic and differential geometry, mathematical and theoretical physics, in the theory of Lie algebras, etc. The list of mentioned subjects shows that my course might be useful for master and Ph.D. students working in different directions.
Motivated undergraduate students can also study this subject. To follow the course one has to know only elementary basic facts from the theory of modular forms (for example, the paragraphs 1-4 of the chapter VII of Serre’s “A Course in Arithmetic” are enough).
The main hero of the course is the Jacobi theta-series. Using it we will construct a lot of concrete examples of Jacobi forms in one or many abelian variables, in particular, Jacobi forms for root systems.
For some of you, who will be successful with the theoretical exercises of the course, I am ready to formulate research problems for Master or Ph.D. thesis. (Ph.D. support might be available at CEMPI in Lille or at the Faculty of Mathematics of National Research University Higher School of Economics in Moscow)...

very interesting course; the subject treated here seems to have wide applications in geometry and number theory; the weekly assignments were challenging at times but very thought provoking and I very much enjoyed myself during the course despite some minor flaws

Very good course. I have really learned a lot from this course. The excercises are carefully selected.

After having had a long lasting personal interest in modular forms, the miracle happened: this MOOC was offered. A huge thanks to Pr.Gritsenko for providing such high quality content and exercises, which go way beyond the classical theory. This is a very challenging and stimulating course which opens into current research areas. Again, a very big thank you to the organisers, if you are interested in the topic and are not working in academia, this is an absolutely unique opportunity !
