AI中文摘要:
我们证明了一个指定投影定理,该定理适用于定义在平面开子集上且满足某些温和几何条件的一类非线性投影。这推广了Davies关于正交投影指定投影的经典结果,以及作者、Chang、McDonald和Taylor最近关于一类特定非线性投影映射的结果。我们还给出了几个几何应用,包括证明某些类别的平面曲线可用于覆盖任意可测集且误差为零测度。
英文摘要:
We prove a prescribed projection theorem for any class of non-linear projections defined on open subsets of the plane which satisfies some mild geometric conditions. This generalizes Davies's classic result on prescribed projections for orthogonal projections, as well as a recent result of authors, Chang, McDonald, and Taylor, on a specific class of non-linear projection maps. We also give several geometric applications, including a proof that certain classes of plane curves can be used to cover arbitrary measurable sets with measure zero error.
