Abstract: In this talk, we discuss the pullback dynamics and statistical solutions for the Boussinesq system involving a dissipative parabolic equation for the velocity field and a conservative hyperbolic equation for the temperature. We adopt the strong topology in space $H^1$ for the velocity field and employ the weak topology in space $L^2$ for the temperature, and then prove that the generated evolution process of the solution mappings possesses a sigma compact pullback attractor in space $H^1 \times L^2$ under this mixed topology. Afterwards, we establish that the evolution process possesses a family of invariant Borel probability measures with supports contained in the obtained pullback attractor. Finally, we prove that a family of probability measures satisfies Liouville's equation and is a statistical solution for the addressed Boussinesq system.
