EXTENSIVE ULTRAPRODUCTS AND HAAR MEASURE**This is a revised form of the paper, entitled “Ultraproduct Haar measure over topological linear spaces,” presented at the Symposium. The author is indebted to Peter Freyd for pointing out that the original formulation was more restricted than it needed to be.

Differentiability Properties

In this paper topological linear spaces are categorised according to the differentiability properties of their continuous convex functions. Mazur's Theorem for Banach spaces is generalised: all separable Baire topological linear spaces are weak Asplund. A class of spaces is given for which Gateaux and Fréchet differentiability of a continuous convex function coincide, which with Mazur's theorem, implies that all Montel Fréchet spaces are Asplund spaces. The effect of weakening the topology of a given space is studied in terms of the space's classification. Any topological linear space with its weak topology is an Asplund space; at the opposite end of the topological spectrum, an example is given of the inductive limit of Asplund spaces which is not even a Gateaux differentiability space.
