The solutions satisfy the ideal slip conditions on the boundary. We underline that there is no restriction on the angular component of velocity. We obtain two kinds of existence results. First, under assumptions necessary for the existence of weak solutions, we prove that the velocity belongs to $W_{4/3}^{2,1}(Ω × (0,T))$, so it satisfies the Serrin condition. Next, increasing regularity of the external force and initial data we prove existence of solutions (by the Leray-Schauder fixed point theorem) such that $v ∈ W_{r}^{2,1}(Ω × (0,T))$ with r > 4/3, and we prove their uniqueness.
