%0 Journal Article %T On the tautological ring of $\M _g$ %A Eduard Looijenga %J Mathematics %D 1995 %I arXiv %R 10.1007/BF01884306 %X We prove among other things that any product of tautological classes of $\M_g$ of degree $d$ (in the Chow ring of $\M _g$ with rational coefficients) vanishes for $d>g-2$ and is proportional to the class of the hyperelliptic locus in degree $g-2$. %U http://arxiv.org/abs/alg-geom/9501010v1
