论文摘要
We give some conditions under which the pressure term in the incompressible Navier-Stokes equations on the entire $d$-dimensional Euclidean space is determined by the formula $\displaystyle \nabla p = \nabla \left(\sum_{i,j=1}^d \mathcal{R}_i \mathcal{R}_j (u_i u_j - f_ {i，j}）\ right）$，其中$ d \ in \ {2，3 \} $，$ {\ textbf {u}}}}：=（u_1，\ ldots，u_d）$是流体速度，$ \ m artbb {f} d} $是强迫张量，对于所有$ k \ in \ {1，\ ldots，d \} $，$ \ mathcal {r} _k $是$ k $ -th riesz transform。
We give some conditions under which the pressure term in the incompressible Navier-Stokes equations on the entire $d$-dimensional Euclidean space is determined by the formula $\displaystyle \nabla p = \nabla \left(\sum_{i,j=1}^d \mathcal{R}_i \mathcal{R}_j (u_i u_j - F_{i,j}) \right)$, where $d \in \{2, 3\}$, ${\textbf{u}} := (u_1, \ldots, u_d)$ is the fluid velocity, $\mathbb{F}:= (F_{i,j})_{1\le i,j\le d}$ is the forcing tensor, and for all $k \in \{1, \ldots, d\}$, $\mathcal{R}_k$ is the $k$-th Riesz transform.
