Polyhedral banach spaces and extensions of compact operators

Israel Journal of Mathematics, 1969
LetX be a polyhedral Banach space whose dual is anL 1(μ) space for some measureμ. Then for each Banach spacesY ⊆Z and each compact operatorT: Y →X there exists a norm preserving compact extension $$\tilde T:Z \to X$$ Z →X.

Approximation by Polyhedral $G$ Chains in Banach Spaces

Zeitschrift für Analysis und ihre Anwendungen, 2014
In a Banach space with the metric approximation property, each compactly supported rectifiable G chain whose boundary is rectifiable as well, is approximatable in the flat norm by a polyhedral G
