19 Nov 2012 In order to ensure the Frechet differentiability of e with respect to y, we need to differen- tiate the Nemytskii operator associated with the nonlinear function g. It is well known, see, e.g. Goldberg et al. [1992], that a norm gap is required whenever g is not affine. That is, g : Lp(?;Rn) > Lq(?;Rn) is differentiable
ON THE DEGENERATION OF THE CLASS OF DIFFERENTIABLE SUPERPOSITION OPERATORS IN FUNCTION SPACES. J. Appell / P. P. Zabrejko. | DOI: https://doi.org/10.1524/anly.1987.7.34.305
We obtain sufficient conditions for the continuity of the general nonlinear superposition operator (generalized Nemytskii operator) acting from the space $C^m (overline Omega )$ of differentiable functions on a bounded domain $Omega $ to the Lebesgue space $L_p (Omega )$ . The values of operators on a function $u

28 Mar 2013 Now, let me answer the question you asked in a comment: Let G:R>R be differentiable and not affine. Let V="Lp"(?), W="R". Then, K=?G(f(x))d?(x) is only Frechet differentiable if p>1. In any case, you need also some additional conditions on G, see Goldberg, Kampowski, Troltzsch: On Nemytskii operators in
21 Sep 2014 In the realm of Sobolev spaces, if k>dim(F)2, for the composition mapping Hk+l(F,R)?Hk(F,F)>Hk(F,R), left translations are Cl and right translations are smooth; i.e., composition is Cl in the right hand side variable, and is smooth in the left hand side variable. This is folklore; for a detailed recent proof see.
