拟Banach数列空间中有界线性非绝对和算子集的可空性

Spaceability of the set of bounded linear non-absolutely summing operators in Quasi-Banach sequence spaces

Daniel Tomaz

摘要:

本文证明了对任意的$0<p<1$,存在$\mathcal{L}\left( \ell_{p};\ell_{p}\right) $的无穷维闭线性子空间,其非零元都是非$(r,s)$ -绝对和算子,其中实数$r,s$具有$1\leq s\leq r<\infty$ .这改善了在\cite{DanielT}中获得的结果。

英文摘要:

In the short note we prove that for every $0<p<1$, there exists an infinite dimensional closed linear subspace of $\mathcal{L}\left( \ell_{p};\ell_{p}\right) $ every nonzero element of which is non $(r,s)$-absolutely summing operator for the real numbers $r,s$ with $1\leq s\leq r<\infty$. This improve a result obtained in \cite{DanielT}.
