摘要：Any μ2-divergence is shown analytically to be absent for a class of actions for Overlap and Domain
Wall Fermions with nonzero chemical potential. All such actions are, however, shown to
violate the chiral invariance. While the parameter M of these actions can be shown to be irrelevant
in the continuum limit, as expected, it is shown numerically that the continuum limit can be
reached with relatively coarser lattices for 1.5 M 1.6.
