Description
A set of equations generalizing the Witten-Veneziano relation
is studied. We present an analytic solution thereof which gives
results, such as eta and eta' masses and decay constants, in
agreement with results previously obtained numerically. The
analytic solution improves the understanding of the description
of the eta-eta' complex. It also supports our approach to U(1)_A
restoration, which links it to the chiral symmetry restoration.
