I am quite familiar with duality transformations for lattice spin systems (i.e. systems with global $O(n)$ symmetry) and pure gauge systems (i.e. local $SU(n)$). However, after searching for a bit, I can't seem to find literature on dual variables for lattice fermions (systems with inner products of grassmann fields). For the spin and gauge cases we do harmonic analysis and fourier expanded the exponential of the action (or a character expansion for the gauge case). Is there an analogous process for lattice actions with grassmann fields? Thanks.
