Abstract

Let Γ\Gamma be a Polish space and let KK be a separable and pointwise compact set of real-valued functions on Γ\Gamma. It is shown that if each function in KK has only countably many discontinuities then C(K)C(K) may be equipped with a TpT_p-lower semicontinuous and locally uniformly convex norm, equivalent to the supremum norm.
