Query: Discrete Dirac-K\"ahler and Hestenes equations   A discrete analogue of the Dirac equation in the Hestenes form is constructed
by introduction the Clifford product on the space of discrete forms. We discuss
the relation between the discrete Dirac-K\"{a}hler equation and a discrete
Hestenes equation.
