A nonlocal discretization of fields
Rafael G. Campos, Eduardo S. Tututi, L. O. Pimentel
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.
