Descriptif
The topic concerns relations among the kappa classes in the tautological ring of the
moduli space of genusgcurves. After a discussion of classical constructions in Wick form, we derivean explicit set of relations obtained from the virtual geometry of the moduli space of stable quotients.In a series of steps, the stable quotient relations are transformed to simpler and simpler forms. Our nal result establishes a previously conjectural set of tautological relations proposed a decade ago byFaber{Zagier.
