关于弱凸多面体的无穷小刚性

On the infinitesimal rigidity of weakly convex polyhedra

Robert Connelly, Jean-Marc Schlenker

摘要:

这里的主要动机是一个问题:是否任何多面体,可以细分成凸片,而不增加一个顶点,并具有相同的顶点作为一个凸多面体,是无穷小刚性。我们证明,这确实是两类多面体的情况下:那些从一个凸多面体的“凹痕”在一个共同的顶点,并与一个自然的细分悬挂最多两个边缘。

英文摘要:

The main motivation here is a question: whether any polyhedron which can be subdivided into convex pieces without adding a vertex, and which has the same vertices as a convex polyhedron, is infinitesimally rigid. We prove that it is indeed the case for two classes of polyhedra: those obtained from a convex polyhedron by ``denting'' at most two edges at a common vertex, and suspensions with a natural subdivision.
