摘要：
Inequalities for QCD functional integrals are used to establish that if the QCD functional integral does not get contributions from a set of zero measure, then the high-temperature chirally restored phase of QCD is effectively symmetric under U(N-f)X U(N-f) rather than SU(N-f)X SU(N-f). If this assumption is correct, there are no effects due to anomalous breaking of U(1)(A) on correlation functions in this phase.
