Lazarev and Lieb showed that finitely many integrable functions from the unit interval to can be simultaneously annihilated in the inner product by a smooth function to the unit circle. Here, we answer a question of Lazarev and Lieb proving a generalization of their result by lower bounding the equivariant topology of the space of smooth circle-valued functions with a certain -norm bound. Our proof uses a variety of motion planning algorithms that instead of contractibility yield a lower bound for the -coindex of a space.

Lazarev 和 Lieb 证明了从单位区间到可以同时被歼灭单位圆的平滑函数的内积。在这里,我们回答了 Lazarev 和 Lieb 的问题,通过将光滑圆值函数空间的等变拓扑下限与某个-范数限制。我们的证明使用了各种运动规划算法,而不是可收缩性,而是为-空间的coindex。
