On Subsequential Averages of Sequences in Banach Spaces

Real Analysis Exchange, 2023
This paper gives a strong contribution to the solution to the conjecture described next. Conjecture 1. Let \(\mathcal{X}\) be a Banach space, and suppose that \(x=\{x_n\}_{n=0}^{\infty}\subseteq\mathcal{X}\). Then the set \[\overline{x}^c=\left\{y\in\mathcal{X}: \exists \text{ a strictly increasing sequence } \{k_n\}\text{ s.t.

On the Boundedness of a Recurrence Sequence in a Banach Space

Ukrainian Mathematical Journal, 2003
The authors consider the recurrence sequence \[ x_n=\sum\limits_{k=1}^\infty A_kx_{n-k}+y_n,\quad n\geq 1, \] \[ x_n=\alpha_n,\quad n\leq 0, \] in a Banach space \(B\), where the sequences \(\{ y_n\}\) and \(\{ \alpha_n\}\) are bounded, \(A_k\) are bounded linear operators, and \(\sum\limits_{k=1}^\infty k^{1+\epsilon}\| A_k\| 0\). It is shown that the

Onc 0 sequences in Banach spaces

Israel Journal of Mathematics, 1989
A Banach space has property (S) if every normalized weakly null sequence contains a subsequence equivalent to the canonical basis of \((c_ 0)\). It is shown that equivalence constants can be choosen independent of the original sequence. It is also shown that property (S) implies property (a) introduced by \textit{A. Pelczynski} [Bull. Acad.

Independent sequences in Banach spaces

Israel Journal of Mathematics, 1982
In every ∞-dimensional separable Banach spaceX there is a fundamental sequence such that no subsequence of it, which is fundamental inX, is independent (“{x n} is fundamental inX” meansX=span {x n}).
