**Завихренность** [[Векторное поле|векторного поля]] - векторное поле $\LARGE a=curl \space g$.

$$\LARGE \textbf{a}=\nabla \times \textbf{g}=(\frac{\partial g_z}{\partial y}-\frac{\partial g_y}{\partial z})\vec{e_x}+(\frac{\partial g_x}{\partial z}-\frac{\partial g_z}{\partial g_x})\vec{e_y}+(\frac{\partial g_y}{\partial x}-\frac{\partial g_x}{\partial y})\vec{e_z}$$
