A model describing the evolution of a liquid crystal substance in the nematic phase is investigated in terms of two basic state variables: the velocity ﬁeld u and the director ﬁeld d, representing the preferred orientation of molecules in a neighborhood of any point in a reference domain. After recalling a known existence result, we investigate the long-time behavior of weak solutions. In particular, we show that any solution trajectory admits a non-empty ω-limit set containing only stationary solutions. Moreover, we give a number of sufﬁcient conditions in order that the ω-limit set contains a single point. Our approach improves and generalizes existing results on the same problem.
