巴拿赫空间上的Cohen强p-和全纯映射

Cohen strongly p-summing holomorphic mappings on Banach spaces

A. Jiménez-Vargas, K. Saadi, J. M. Sepulcre

摘要:

设$E$和$F$是复巴拿赫空间,$U$是$E$和$1\leq p\leq\infty$的开子集.我们引入并研究了从$U$到$F$的Cohen强$p$ -求和全纯映射的概念,强$p$ -求和线性算子的全纯版本。对于这类映射,我们建立了Pietsch控制/因子分解定理,并分析了它们从$\mathcal{G}^\infty(U)$($\mathcal{H}^\infty(U)$的标准预对偶)的线性化及其在$\mathcal{H}^\infty(U)$上的转置.对于由这类映射构成并赋以自然范数$d_p^{\mathcal{H}^\infty}$的空间$\mathcal{D}_p^{\mathcal{H}^\infty}(U,F)$,我们证明了它是由强$p$ -和线性算子的理想复合生成的有界全纯映射的正则Banach理想.此外,我们还证明了空间$(\mathcal{D}_p^{\mathcal{H}^\infty}(U,F^*),d_p^{\mathcal{H}^\infty})$是张量积空间$\mathcal{G}^\infty(U)\otimes F$的完备化的对偶空间,该空间具有Chevet-Saphar范数$g_p$。

英文摘要:

Let $E$ and $F$ be complex Banach spaces, $U$ be an open subset of $E$ and $1\leq p\leq\infty$. We introduce and study the notion of a Cohen strongly $p$-summing holomorphic mapping from $U$ to $F$, a holomorphic version of a strongly $p$-summing linear operator. For such mappings, we establish both Pietsch domination/factorization theorems and analyse their linearizations from $\mathcal{G}^\infty(U)$ (the canonical predual of $\mathcal{H}^\infty(U)$) and their transpositions on $\mathcal{H}^\infty(U)$. Concerning the space $\mathcal{D}_p^{\mathcal{H}^\infty}(U,F)$ formed by such mappings and endowed with a natural norm $d_p^{\mathcal{H}^\infty}$, we show that it is a regular Banach ideal of bounded holomorphic mappings generated by composition with the ideal of strongly $p$-summing linear operators. Moreover, we identify the space $(\mathcal{D}_p^{\mathcal{H}^\infty}(U,F^*),d_p^{\mathcal{H}^\infty})$ with the dual of the completion of tensor product space $\mathcal{G}^\infty(U)\otimes F$ endowed with the Chevet--Saphar norm $g_p$.
