q there is a function g_ (p, a) of class H_p so that its derivative does not belong to the space H_α.
A first objective of the work is to choose g_ (p, a) independent of α and to show that the set of all these functions g_p is G_δ and a dense subset in the space H_p (2nd category). Also consider the localized forms of this result as well as replace the H_p space with spaces of the form ⋂_ (β
