SUMMARY
The discussion centers on the mathematical concept that if the divergence of a vector field is zero, it implies that the vector field can be expressed as the curl of another vector field. Specifically, the divergence equation is given by \(\nabla\cdot u=\frac{\partial u_x}{\partial x}+\frac{\partial u_y}{\partial y}+\frac{\partial u_z}{\partial z}\), and the curl can be derived from the components of the vector field. To find the original vector field, one must set up a system of partial differential equations (PDEs) based on the curl equations and solve for the components.
