A nonlocal discretization of fields
arXiv:hep-lat/0012015 · doi:10.1142/S0217751X01005109
Abstract
A nonlocal method to obtain discrete classical fields is presented. This technique relies on well-behaved matrix representations of the derivatives constructed on a non--equispaced lattice. The drawbacks of lattice theory like the fermion doubling or the breaking of chiral symmetry for the massless case, are absent in this method.
