= Constant-field relativistic Lorentz-force solution

For a constant <electromagnetic field tensor>, the <relativistic Lorentz force> is a constant-coefficient linear system on <four-velocity>, with solution
$$
u(\tau)=\exp\!\left(\frac qmF\tau\right)u(0).
$$
The electric-type blocks of $F$ generate hyperbolic rotations, while magnetic-type blocks generate ordinary rotations.
