Lipschitz extensions of linear operators

Abstract

Let E,F,E0E, F, E_0 be Banach spaces, with E0E_0 a subspace of EE. For a maximal Banach operator ideal A\mathcal{A}, we show that a linear operator from E0E_0 to FF can be extended to a linear operator from EE to FF that belongs to A\mathcal{A} if and only if it can be extended to a Lipschitz map from EE to FF belonging to a wide class of Lipschitz Banach operator ideals related with A\mathcal{A}. As a consequence, we show that linear operators with special Lipschitz factorization through (Γ)\ell_{\infty}(\Gamma) has analogous linear factorization through (Γ)\ell_{\infty}(\Gamma).
