Speaker: Bin Zhang, Sichuan University, China

Abstract: This is joint work with Li Guo and Sylvie Paycha. In this talk, we will address the application of Connes-Kreimer's renormalization to toric varieties. We will first construct the hopf algebra of cones, and the algebra homomorphism from this hopf algebra to the algebra of meromorphic functions. Then we will use renormalization precedure to get an easy way to calculate the Todd classes of toric varieties.
