Suppose we have a vector field $vec{f}(x,y,z)$ defined everywhere in space except a certain region say $(y=3)$. We also know divergence of $vec{f}(x,y,z)$ is zero at all points where $vec{f}$ is defined. From this information, is it valid to say that: $$vec{f}(x,y,z)=nabla times vec{g}(x,y,z)$$ at all points wherever $vec{f}(x,y,z)$ is defined? Why? Why not?
