DESCRIPTION:Bianca Viray\nLet d1 and d2 be discriminants of quadratic imag
 inary orders and let J(d1\,d2)^2 denote the product of differences of CM j
 -invariants with discriminants d1 and d2. In 1985\, Gross and Zagier gave 
 an elegant formula for the factorization of the integer J(d1\,d2) in the c
 ase that d1 and d2 are relatively prime and discriminants of maximal order
 s. In this talk\, I will explain how we generalize their methods and give 
 a complete factorization in the case that d1 is squarefree and d2 is any d
 iscriminant and a partial factorization in all other cases. If time permit
 s\, I will explain how this leads us to a conjectural formula for when the
  conductors of d1 and d2 are relatively prime. This is joint work with Kri
 stin Lauter.
