2(D)-COMPONENT FERMION ON A (1-DIMENSIONAL EUCLIDEAN LATTICE WITH DISCRETE CHIRAL SYMMETRIES(D))

We formulate the Dirac equation by a proficient method on a (1+D)-dime nsional Euclidean lattice and get some new results. First, the obtaine d dispersion relation of the lattice fermion has no extra poles. Secon d, the components of the fermion is 2(D), which should be compared to the 2(D+1) of the Kogut-Susskind (KS) fermion. Furthermore we can expl icitly show that the theory has the KS discrete chiral symmetry. All t he lattice fermions tend to the usual fermions on continuous spacetime .
