Properties and temperature behavior of pi and sigma bound states are studied
in the framework of the nonlocal model with a separable interaction kernel
based on the quark Dyson-Schwinger and the meson Bethe-Salpeter equations.
M_pi(T), f_pi(T), M_sigma(T) and Gamma_{sigma -> pi pi}(T) are considered above
and below the deconfinement and chiral restoration transitions.
