  We investigate the possible restoration of chiral and axial symmetries across
the phase transition at finite temperature and chemical potential, by analyzing
the behavior of several physics quantities, such as the quark condensates and
the topological susceptibility, the respective derivatives in order to chemical
potential, and the masses of meson chiral partners. We discuss whether only
chiral symmetry or both chiral and axial symmetries are restored and what is
the role of the strange quark. The results are compared with recent lattice
results.
