Values of Green functions at CM points

by Stephen Kudla | University of Toronto
Time: 14:10  (Wednesday, Feb. 02, 2011)
Location: BA6183, Bahen Center, 40 St. George St.
Abstract:
I will survey of various generalizations of the classic Gross-Zagier formula giving an explicit formula for the factorization of singular moduli. The Green functions on Shimura varieties of orthogonal type are constructed via the Borcherd's regularized theta lifts. Their special values at various types of CM points can be expressed in terms of derivatives of Fourier coefficients of incoherent Eisenstein series. In the case of `big' CM points, these results are joint work with Jan Bruinier and Tonghai Yang.
