Abstract: | Given real Banach spaces X and Y, let C
wbu1(X, Y) be the space, introduced by R.M. Aron and J.B. Prolla, of C
1 mappings from X into Y such that the mappings and their derivatives are weakly uniformly continuous on bounded sets. We show that f ∈ C
wbu1(X, Y) if and only if f may be written in the form f = g ∘ S, where the intermediate space is normed, S is a precompact operator, and g is a Gateaux differentiable mapping with some additional properties. |
