Maxim KAZARYAN (Steklov Institute and IUM, Moscow): Hodge integrals and the tautological ring of the moduli space of curves . The cohomology ring of the (compactified) moduli spaces of algebraic curves has extremely complicated structure and there is no hope to get its complete description. It happens, however, that cohomology classes which are interesting from the point of view of applications form a relatively small subring of the whole cohomology ring and its description is much simpler. ...
