The injective hull of ideals of weighted holomorphic mappings

We study the injectivity of normed ideals of weighted holomorphic mappings. To be more precise, the concept of injective hull of normed weighted holomorphic ideals is introduced and characterized in terms of a domination property. The injective hulls of those ideals -- generated by the procedures of composition and dual -- are described and these descriptions are applied to some examples of such ideals. A characterization of the closed injective hull of an operator ideal in terms of an Ehrling-type inequality -- due to Jarchow and Pelczyński -- is established for weighted holomorphic mappings.

The Bishop--Phelps--Bollobás property for weighted holomorphic mappings

Given an open subset $U$ of a complex Banach space $E$, a weight $v$ on $U$ and a complex Banach space $F$, let $H^\infty_v(U,F)$ denote the Banach space of all weighted holomorphic mappings from $U$ into $F$, endowed with the weighted supremum norm. We introduce and study a version of the Bishop--Phelps--Bollobás property for $H^\infty_v(U,F)$ ($WH^\infty$-BPB property, for short). A result of Lindenstrauss type with sufficient conditions for $H^\infty_v(U,F)$ to have the $WH^\infty$-BPB property for every space $F$ is stated. This is the case of $H^\infty_{v_p}(\mathbb{D},F)$ with $p\geq 1$, where $v_p$ is the standard polynomial weight on $\mathbb{D}$. The study of the relations of the $WH^\infty$-BPB property for the complex and vector-valued cases is also addressed as well as the extension of the cited property for mappings $f\in H^\infty_v(U,F)$ such that $vf$ has relatively compact range in $F$.
