非欧空间中小型柔性多面体的风箱猜想

The bellows conjecture for small flexible polyhedra in non-Euclidean spaces

Alexander A. Gaifullin

AI总结:

针对非欧空间中柔性多面体体积是否恒定的问题,本文证明在维数不低于3的球面和Lobachevsky空间中,棱长足够小的柔性多面体均满足风箱猜想。

摘要:

风箱猜想断言,任何维数为3或更高的柔性多面体在弯曲过程中体积保持恒定。该猜想已在维数3及更高的欧几里得空间中的柔性多面体,以及奇维Lobachevsky空间中的有界柔性多面体上得到证明。在所有维数3及更高的开半球中,已知存在风箱猜想的反例。本文的目的是证明,尽管如此,对于球面或Lobachevsky空间中维数大于或等于3且棱长足够小的所有柔性多面体,风箱猜想仍然成立。

英文摘要:

The bellows conjecture claims that the volume of any flexible polyhedron of dimension 3 or higher is constant during the flexion. The bellows conjecture was proved for flexible polyhedra in the Euclidean spaces of dimensions 3 and higher, and for bounded flexible polyhedra in the odd-dimensional Lobachevsky spaces. Counterexamples to the bellows conjecture are known in all open hemispheres of dimensions 3 and higher. The aim of this paper is to prove that, nonetheless, the bellows conjecture is true for all flexible polyhedra in either spheres or Lobachevsky spaces of dimensions greater than or equal to 3 with sufficiently small edge lengths.
