This work focuses on important step in quantitative topology: given homotopic mappings from to of Lipschitz constant , build the (asymptotically) simplest homotopy between them (meaning having the least Lipschitz constant). The present paper resolves this problem for the first case where Hopf invariant plays a role: , , constructing a homotopy with Lipschitz constant .

从 3-sphere 到 2-sphere 映射的 Lipschitz 同伦
这项工作的重点是定量拓扑中的重要步骤:给定同伦映射至Lipschitz 常数,在它们之间建立(渐近)最简单的同伦(意味着具有最小的 Lipschitz 常数)。本文针对 Hopf 不变量起作用的第一种情况解决了这个问题:,, 用 Lipschitz 常数构造同伦.
