Pullback attractor for heat convection problem in a micropolar fluid. (English) Zbl 1189.35030
Summary: We consider a two-dimensional micropolar fluid flow heated from below. We assume that the temperature of the lower part of the boundary is a function of time. That leads to the non-autonomous system of equations. We show the existence of the pullback attractor for the problem. Next, the dimension of the attractor is estimated from above.
