A path-integral representation of the free one-flavour staggered-fermion   determinant
  Lattice fermion actions are constructed with path integrals which are equivalent to the free one-flavour staggered fermion determinant. The Dirac operators used are local and have an identical spectrum of states to the staggered theory. Operators obeying a generalised Ginsparg-Wilson relation are developed.
