摘要：
It was known in 1600s that a cube contains a hole that is large enough for its copy to pass through. In 1700s, Niewland asked a refined question: whether a polytope contains a hole that can be passed through by a scaled copy of the polytope. The largest possible scalar is called the Niewland constant. So far, we only know the exact value of the Niewland constants for two polytopes: the cube and the Noperthedron. In this talk, I will discuss a method to calculate the Niewland constants in general.
