Abstract
The behavior of and in hot strange quark matter in weak equilibrium with temperature, is investigated within the SU(3) Nambu-Jona-Lasinio [NJL] model. Possible manifestations of restoration of symmetries, by temperature or density, in the behavior of and are discussed. The role played by the combined effect of temperature and density in the nature of the phase transition and meson behavior is also analyzed.
