Higher order Lipschitz Sandwich theorems

We investigate the consequence of two Lip(γ) functions, in the sense of Stein, being close throughout a subset of their domain. A particular consequence of our results is the following. Given K0 > ε > 0 and γ > η > 0 there is a constant δ = δ(γ, η, ε, K0) > 0 for w...
