Sobolev embedding theorem and subanalytic measures

Guillaume Valette

We focus on Borel measures that have a globally subanalytic density function. We prove, given such a measure $μ$ on a set $A$ and a globally subanalytic mapping $Φ : A \to Ω$ , with $Ω…

Inner Lipschitz approximation in o-minimal structures

Nhan Nguyen, Anna Valette, Guillaume Valette

Given an o-minimal structure, we show that every definable (in this structure) mapping that is Lipschitz with respect to the inner metric can be approximated by $C^{1}$ map…

Density of Neumann regular smooth functions in Sobolev spaces of subanalytic manifolds

Guillaume Valette

We give characterizations of the bounded subanalytic $C^{\infty}$ submanifolds $M$ of $R^{n}$ for which the space of Neumann regular functions is dense in Sobolev sp…
