The study demonstrates that Lipschitz spaces are linearly isomorphic in non-porous sets, indicating significant mathematical implications.
Let M be a subset of Rⁿ. If M is not porous, in particular if it has positive n-dimensional Lebesgue measure, we prove that the Lipschitz spaces Lip₀(M) and Lip₀(Rⁿ) are linearly isomorphic. The result also holds more generally if Rⁿ is replaced with a Carnot group equipped with its Carnot-Carathéodory metric.
