Let Ξ± β‘ {Ξ± n } β n=0 be a weight sequence and let W Ξ± denote the associated unilateral weighted shift on 2 (Z + ). In this paper we prove that if Ξ± is eventually increasing, then W Ξ± is M-hyponormal and that if Ξ± has exactly two subsequential limits such that the larger one is different from the spe
