On p-summability in weighted Banach spaces of holomorphic functions

Abstract

Given an open subset $U$ of a complex Banach space $E$, a weight $v$ on $U$, and a complex Banach space $F$, let $\Hv(U,F)$ denote the Banach space of all weighted holomorphic mappings $f:U\to F$, under the weighted supremum norm ${\Vert f\Vert }_v:=\sup \left\{v(x)\Vert f(x)\Vert :x\in U\right\}$. In this paper, we introduce and study the class $Π_p^{\Hv}(U,F)$ of $p$-summing weighted holomorphic mappings. We prove that it is an injective Banach ideal of weighted holomorphic mappings. Variants for weighted holomorphic mappings of Pietsch Domination Theorem, Pietsch Factorization Theorem and Maurey Extrapolation Theorem are presented. We also identify the spaces of $p$-summing weighted holomorphic mappings from $U$ into $F^{\ast }$ under the norm $π^{\Hv}_p$ with the duals of $F$-valued $\Hv$-molecules on $U$ under a suitable version $d^{\Hv}_{p^*}$ of the Chevet--Saphar tensor norms.
