Abstract:
It has been shown that effective fermion vertices appear in lattice gravity associated with fermions. These vertices are generated by gravitational instantons, similar to the appearance of effective fermion vertices in the Yang–Mills theory because of the existence of zeroth fermion modes associated with instantons.
