Abstract:Sufficient conditions are given on a Banach space X which ensurethat embeds in L(X), the space of all bounded linear operatorson X. A basic sequence en is said to be quasisubsymmetric iffor any two increasing sequences (kn) and (ln) of positive integerswith (kn) ≤ (ln) for all n, (Formula) dominates (Formula). If a Banach space X has a seminormalized quasisubsymmetric basis then l{infty} embedsin l(X). 2000 Mathematics Subject Classification 46B28 (primary),46B03 (secondary).
