We consider  Schrodinger operators with complex decaying
potentials on the lattice. Using some classical results from Complex Analysis we  obtain some trace formulae and using them estimate globally all zeros of the  Fredholm determinant in terms of the potential. It is jointly with Ari Laptev, London.
