“…If we now find on the interval (t 1 , t 1 + Δh] the control u(t) according to equation m i=0 B i u(t − ih) = 0, t ∈ (t 1 , t 1 + Δh], with initial condition (5.5) (which ensures that this equation does have a solution [21,22]), then due to (5.8) we will have (2.4). This completes the proof of Theorem 4.…”
