Szlenk indices and uniform homeomorphisms

G. Godefroy, N. J. Kalton, G. Lancien

We prove some rather precise renorming theorems for Banach spaces with Szlenk index $ω_{0}$ . We use these theorems to show the invariance of certain quantitative Szlenk-type indices…

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…

A solution to the problem of $L^{p} -$ maximal regularity

N. J. Kalton, G. Lancien

We give a negative solution to the problem of the $L^{p}$ -maximal regularity on various classes of Banach spaces including $L^{q}$ -spaces with $1 < q \neq = 2 < + \infty$ .
