标题： $L^p$ coarse Baum-Connes conjecture via $C_{0}$ coarse geometry

摘要： 在本文中，我们通过$C_{0}$粗结构研究$p\in [1,\infty)$的$L^{p}$粗 Baum-Connes 猜想，这是度量空间上有界粗结构的改进。 我们证明了$L^{p}$粗 Baum-Connes 猜想的$C_{0}$版本，并因此构建了该猜想的障碍群。 作为应用，我们表明在有限渐进行为维数假设下障碍消失，从而给出了在此情况下$L^{p}$粗 Baum-Connes 猜想的新证明。 显示英文摘要

摘要： In this paper, we investigate the $L^{p}$ coarse Baum-Connes conjecture for $p\in [1,\infty)$ via $C_{0}$ coarse structure, which is a refinement of the bounded coarse structure on a metric space. We prove the $C_{0}$ version of the $L^{p}$ coarse Baum-Connes conjecture and thus construct an obstruction group for the conjecture. As an application, we show that the obstructions vanish under the assumption of finite asymptotic dimension, and hence give a new proof of the $L^{p}$ coarse Baum-Connes conjecture in this case.
