Query: Dirac-Kaehler Fermion from Clifford Product with Noncommutative
  Differential Form on a Lattice   We formulate Dirac-Kaehler fermion action by introducing a new Clifford
product with noncommutative differential form on a lattice. Hermiticity of the
Dirac-Kaehler action requires to choose the lattice structure having both
orientabilities on a link. The Kogut-Susskind fermion and the staggered fermion
actions are derived directly from the Dirac-Kaehler fermion formulated by the
Clifford product. The lattice QCD action with Dirac-Kaehler matter fermion is
also derived via an inner product defined by the Clifford product.
