Uniform Contractification [PDF]

Canadian Mathematical Bulletin, 1978
AbstractLet (X, τ) be a metrizable space and {fn: n = 1,2,…} be a commuting family of continuous mappings on X with a common fixed point ξ ∈ X such that (I) for each k = l, 2, … and (II) Then for each c ∈ (0,1), there exists a metric d on X inducing the topology τ such that , for all x, y∈X and n = l, 2, ….

Uniform Differentiability

Real Analysis Exchange, 2012
In this paper, the notion of uniformly strong differentiable functions is introduced and the Henstock and McShane integrals in terms of equi-integrability and uniform strong differentiability are investigated. The proofs rely on related tools in measure theory.
