We show that an infinite Toeplitz+Hankel matrix $T(\varphi ) + H(\psi )$ generates a bounded [compact] operator on $\ell ^p(\mathbb N _0)$ with $1\leq p\leq \infty $ if and only both $H(\psi are [compact]. also give anal
Numerous adverse factors are acting in the prenatal, perinatal and postnatal period of life and may be the cause of later mild or severe deviations from normal psychomotor development. Therefore, it is crucial to identify infants with neurological risk factors and infants that already have a delay from orderly development, in order to immediately initiate the rehabilitation process. The aim of ...

Let be innnite cardinals and let be a set of cardinality. The bounded permutation group B ((), or simply B , is the group consisting of all permutations of which move fewer than points in. We say that a permutation group G acting on is a supplement of B if B G is the full symmetric group on. In 7], Macpherson and Neumann claimed to have classiied all supplements of bounded permutation groups. S...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
