Scalar Fields
  > s.a. klein-gordon fields; wave equations [discrete].
  * λφ^4 theory:
    It becomes the free scalar field theory when the spacing goes to zero; Possible
    reactions are (1) The theory cannot be considered seriously; (2) The lattice approximation
    is ok but there just isn't any λφ4
    continuum theory (no self-interacting field, except maybe coupled to other fields);
    (3) Fix the problem [Klauder].

Fermions, Spinor Fields
  > s.a. dirac fields; ising model; spinors
  and 2-spinors; spin models; {random lattices below}.
  * In lattice gauge theory:
    There is a problem, the absence of a chiral anomaly (no-go Nielsen-Ninomiya
    theorem); > s.a. spinors.
  * Fermion doubling:
    The appearance of spurious fermion states in lattice theories;
  > s.a. lattice theories [non-commutative lattices]; loop
    quantum gravity; Wikipedia page.
  * Supersymmetric models: The
    violation of the Leibniz rule on a lattice is an obstruction for constructing
    a lattice supersymmetric model.
