Abstract

Let us consider an initial data v0v_0 for the classical 3D Navier-Stokes equation with vorticity belonging to L32L2L^{\frac 32}\cap L^2. We prove that if the solution associated with v0v_0 blows up at a finite time TT^\star, then for any p]4,[, q1[1,2[, μ>0, q2[2,(1/p+μ)1[, κ]1,[p\in]4,\infty[,~q_1\in[1,2[,~\mu>0, ~q_2\in\bigl[2,\bigl(1/p+\mu\bigr)^{-1}\bigr[,~\kappa\in ]1,\infty[, and any unit vector ee, the LpL^p estimate in time of (v(t)e)R3L3pp2p+(v(t)e)R3(B˙q1,κμ+2p+2q11)h(B˙q2,κ1q2μ)vp\bigl\|(v(t)|e)_{\mathbb{R}^3}\bigr\|_{L^{\frac{3p}{p-2}}}^p +\bigl\|(v(t)|e)_{\mathbb{R}^3}\bigr\|^p_{ \bigl(\dot{B}^{\mu+\frac2p+\frac2{q_1}-1}_{q_1,\kappa}\bigr)_{\rm h} \bigl(\dot{B}^{\frac1{q_2}-\mu}_{q_2,\kappa}\bigr)_{\rm v}} blows up at TT^\star.
