Properties of a New Class of Lattice Dirac Operators

Kazuo Fujikawa, Masato Ishibashi

A new class of lattice Dirac operators $D$ have been recently proposed on the basis of the generalized Ginsparg-Wilson relation, ${\gamma }_5({\gamma }_{5}D)+({\gamma }_{5}D){\gamma }_5=2a^{2k+1}({\gamma }_{5}D{)}^{2k+2}$,…
