Abstract

We study a systematic way to produce a Lipschitz operator ideal from a Banach linear operator ideal A\mathcal A. For maximal and minimal operator ideals A\mathcal A, the Lipschitz maximal hull and minimal kernel of the Lipschitz operator ideals Lip0ALip0\text{Lip}_0 \circ \mathcal A \circ \text{Lip}_0 are investigated, respectively. Using ultraproduct techniques, we obtain the Lipschitz version of a result of K\"ursten and Piestch which characterizes the maximal hull of any Lipschitz operator ideal. Among other results, we characterize the linear operators which belong to Lip0ALip0\text{Lip}_0\circ \mathcal A\circ \text{Lip}_0 which, in many cases, they are precisely those which are in A\mathcal A. In particular, we give some cases in which a nonlinear factorization of linear operators implies a linear one, in terms of a given Banach linear operator ideal A\mathcal A.

25 pages. We modify and fix some proof of the older version. Also, some proofs have been written more carefully in order to fill gaps. Also, former Section 3 have been divide in two Sections to improve readibility of the manuscript
