### Tautological Ring of Moduli Spaces of Curves

**Colloquium**

Speaker: | Hao Xu, Department of Mathematics, Harvard University |

Location: | 1147 MSB |

Start time: | Mon, Apr 12 2010, 4:10PM |

We will survey the recent progress on the structure of tautological ring of moduli space of curves. We will talk about our proof (with Prof. Kefeng Liu) of the Faber intersection number conjecture and recursion formulae of higher Weil-Petersson volumes of moduli spaces of curves. The latter is motivated by the work of Prof. Mulase and Safnuk.
