Original abstract: It is known from path integral studies of the chiral anomaly that the fermion measure has to depend on gauge fields interacting with the fermion. It is argued here that in the presence of axion fields interacting with the fermion, they too may be involved in the measure, with unexpected consequences.

    This paper claims that the Peccei-Quinn solution to the strong CP problem doesn't work. I listed it for review in the hope that the mistake in the argument could be precisely identified.
