$W^{1,1}$平面Sobolev同胚的同态逼近

Diffeomorphic Approximation of $W^{1,1}$ Planar Sobolev Homeomorphisms

Stanislav Hencl, Aldo Pratelli

摘要:

令$Ω\subseteq\mathbb R^2$是域,并且令$f\in W^{1,1}(Ω,\mathbb R^2)$是同胚(在$Ω$和$f(Ω)$之间)。则在$W^{1,1}(Ω,\mathbb R^2)$中存在一致收敛于$f$的光滑同态序列$f_k$.

英文摘要:

Let $Ω\subseteq\mathbb R^2$ be a domain and let $f\in W^{1,1}(Ω,\mathbb R^2)$ be a homeomorphism (between $Ω$ and $f(Ω)$). Then there exists a sequence of smooth diffeomorphisms $f_k$ converging to $f$ in $W^{1,1}(Ω,\mathbb R^2)$ and uniformly.
