Query: Discrete Dirac-K\"ahler equation and its formulation in algebraic form   A relationship between the discrete Dirac-K\"ahler equation and discrete
analogues of some Dirac type equations in the geometric spacetime algebra is
discussed. We show that a solution of the discrete Dirac-K\"ahler equation can
be represented as the sum and difference of solutions of discrete Dirac type
equations with the corresponding sign of the mass term.
