Query: Trace formulae for Schr\"odinger operators with complex-valued
  potentials on cubic lattices   We consider Schr\"odinger 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.
