DESCRIPTION:Title: Rational curves on K3 surfaces\n\nAbstract:It is conject
 ured that there are infinitely many rational curves on every projective K3
  surface. A large part of this conjecture was proved by Jun Li and Christi
 an Liedtke: there are infinitely many rational curves on every projective 
 K3 surface of odd Picard rank. Over complex numbers\, there are a few rema
 ining cases: K3 surfaces of Picard rank two excluding elliptic K3's and K3
 's with infinite automorphism groups and K3 surfaces with two particular P
 icard lattices of rank four. We have settled these leftover cases and also
  generalized the conjecture to curves of high genus. This is a joint work 
 with Frank Gounelas and Christian Liedtke.\n
