The course is mainly devoted to the classical theory of Riemann surfaces and complex algebraic curves, founded by Riemann, Abel, Jacobi, Weierstrass, Hurwitz and others. This fundamental theory is the basis of algebraic geometry, the theory of complex manifolds and other important parts of contemporary mathematics. Lately, the theory of Riemann surfaces has played a remarkable role in mathematical physics. Some of these applications will also be considered in the course.
