In this paper, we consider the pullback asymptotic behaviors of weak solutions for the 2D non-autonomous Non-Newtonian micropolar fluids. Employing the methods of ℓ-trajectories in [31], we first establish the existence of a finite dimensional pullback attractor and a pullback exponential attractor for the process associated with (1.2)-(1.4) in the phase space . Then we construct a pullback exponential attractor for the process associated with (1.2)-(1.4) in the original phase space .

在本文中,我们考虑了二维非自治非牛顿微极性流体的弱解的回拉渐近行为。采用的方法ℓ -trajectories在[31],我们首先建立一个有限维拉回吸引子的过程的存在和拉回指数吸引 与相空间中的(1.2)-(1.4)相关 。然后我们为该过程构造一个回调指数吸引子 与原始相空间中的(1.2)-(1.4)相关 。
