DESCRIPTION:For a smooth and projective curve\, Gross and Schoen\nhave con
 structed a (modified and cohomologically trivial) diagonal cycle.\nIn modu
 lar curve case\, Gross and Kulda have conjectured that the heights\nof the
  Hecke components  of this cycle are related to the derivatives\nof triple
  L-series of  modular forms. In this talk\, I will  outline a\nproof of th
 e conjecture\,  and explain some consequences in\nBeilinson-Bloch conjectu
 re and Bogomolov conjecture.
