我们表明标量平均曲率刚性的翘曲产品的圆形领域的尺寸至少为2在紧凑的间隔配备了严格的日志凹翘曲函数。这将Cecchini-Zeidler的早期结果推广到所有维度。此外,我们证明了标量曲率刚性的圆形领域的尺寸至少为3的两个对映点删除。这解决了格罗莫夫的“四个讲座”中的一个问题。我们的论点是基于自旋几何。
We show scalar-mean curvature rigidity of warped products of round spheres of dimension at least 2 over compact intervals equipped with strictly log-concave warping functions. This generalizes earlier results of Cecchini-Zeidler to all dimensions. Moreover, we show scalar curvature rigidity of round spheres of dimension at least 3 with two antipodal points removed. This resolves a problem in Gromov's ''Four Lectures'' in all dimensions. Our arguments are based on spin geometry.
