摘要

给定任意f在W中Ω∧R n到∆∧R上的一个局部有限片段仿射同纯，1≤p <∞和任意ε >，我们构造了一个光滑内射映射f _使得‖f−f _‖W (Ω，R) < ε。

Smooth homeomorphic approximation of piecewise affine homeomorphisms

Given any f a locally finitely piecewise affine homeomorphism of Ω ⊂ R n onto ∆ ⊂ R in W , 1 ≤ p < ∞ and any ε > 0 we construct a smooth injective map f̃ such that ‖f − f̃‖W (Ω,R) < ε.
