In many applications to differential, integral, or functional equations, more than just continuity the operator (1.1) is required in order to make use of the basic principles of nonlinear analysis. For instance, in order to solve the functional equation f(t) = h(t, f(t)) with respect to f ∈ (X, ‖ · ‖) ⊂ F (I), one could try to apply the classical Banach fixed point theorem by imposing on H : X −→ X a global Lipschitz condition. However, it is well known that this leads to a strong degeneracy for the corresponding function h, the global Lipschitz condition on operator (1.1) implies that h must have the form
