Properties of a New Class of Lattice Dirac Operators
Abstract
A new class of lattice Dirac operators D have been recently proposed on the basis of the generalized Ginsparg-Wilson relation, γ5(γ5 D) + (γ5 D)γ5 =2a2k+1(γ5 D)2k+2, where k is a non-negative integer. We discuss the index theorem and locality properties for this general class of lattice Dirac operators.
