The well-known Cameron--Johnson theorem asserts that the equation \(\dot x = \mathcal{A}\left( t \right)x\) with a recurrent (Bohr almost periodic) matrix \(\mathcal{A}\left( t \right)\) can be reduced by a Lyapunov transformation to the equation \(\

The paper deals with bounded (on? or?) solutions of the equation with recurrent (almost periodic) coefficients. We show that the zero solution of this equation is uniformly stable (bistable) if and only if all its solutions and the solutions of its l
