Path differentiation: further unification

Udayan Darji, Michael Evans (1995)

Fundamenta Mathematicae

A. M. Bruckner, R. J. O'Malley, and B. S. Thomson introduced path differentiation as a vehicle for unifying the theory of numerous types of generalized differentiation of real valued functions of a real variable. Part of their classification scheme was based on intersection properties of the underlying path systems. Here, additional light is shed on the relationships between these various types of path differentiation and it is shown how composite differentiation and first return differentiation...

Regular fractional iteration of convex functions

Marek Kuczma (1980)

Annales Polonici Mathematici

The existence of a unique C 1 solution φ of equation (1) is proved under the condition that f: I → I is convex or concave and of class C 1 in I, 0 < f(x) < x in I*, and f’(x) > 0 in I. Here I = [0, a] or [0, a), 0 < a ≤ ∞, and I* = I 0.
