    On uniformly differentiable mappings from l(infinity) (Gamma)

  • Original language description

    In 1970 Haskell Rosenthal proved that if X is a Banach space, I' is an infinite index set, and T : l(infinity)(Gamma) -- X is a bounded linear operator such that inf-yEr 11T(67)11 > 0 then T acts as an isomorphism on l(infinity)(Gamma'), for some r, C P of the same cardinality as P. Our main result is a nonlinear strengthening of this theorem. More precisely, under the assumption of GCH and the regularity of I', we show that if F : Bl(infinity)(r) X is uniformly differentiable and such that infer 11F(e-y) F(0)11 > 0 then there exists x E l(infinity)(Gamma) such that dF(x)[.] is a bounded linear operator which acts as an isomorphism on l(infinity)(Gamma), for some Gamma' C r of the same cardinality as r.
