I have a question about a rotating vector field:
if there is a vector ##A^i(t_0)## at the origin in coordinate space ##IR^3## , when ##t≥t_0##, the vector rotates with a changing angular-velocity ##ω^i(t)##. then we can get a rotating vector field ##A^i(t)##. then how to describe ##A^i(t)## using angular-velocity ##ω^i(t)##?
Further more, if ##\theta^i(t_1)\doteq \int^{t_1}_{t_0}\omega^i(t)dt=0##, then can we assert that ##A^i(t_1)=A^i(t_0)##?
