... and only if lim inf n λ n n > 0. Proof. The sufficiency part of the proof can be obtained using the same technique as the sufficiency part of the proof of Theorem 3 in Savas [25]. For the necessity ... ˆs(∆ r ) instead of ˆs(∆ r λ ). The proof of the following theorem is easily obtained by using the same techniques of Theorem 2 in Savas [25], therefore we give it without proof. The...
