DESCRIPTION:The Donagi conjecture states that the Prym map is 
 injective at a double cover of a curve if the curv
 e does not admit a morphism of degree less or equa
 l to 4 onto the projective line. The talk focusses
  on 2 subjects\, I will explain why the existing p
 roofs of the tetragonal construction do not genera
 lize and then outline the proof of a generalizatio
 n which give counterexamples to the conjecture. Th
 is is joint work with Elham Izadi.\n\n
