Subspaces of c_0 and Lipschitz isomorphisms
G. Godefroy, N. J. Kalton, G. Lancien
We show that the class of subspaces of c_0 is stable under Lipschitz isomorphisms. The main corollary is that any Banach space which is Lipschitz isomorphic to c_0 is linearly isom…

Operators between subspaces and quotients of L1
G. Godefroy, N. Kalton, D. Li
We provide an unified approach of results of L. Dor on the complementation of the range, and of D. Alspach on the nearness from isometries, of small into isomorphisms of L1. We int…
