Lecture 1: Manifolds and triangulations I will introduce the triangulation problem for manifolds: When is a topological manifold (a space that looks locally like Euclidean space) homeomorphic to a ...

The findings not only broaden the comprehension of higher-order topological phases but also provide new insights into the band theory within the manifold of the Brillouin real projective space.

A groundbreaking study led by researchers from Southeast University, the Chinese Academy of Sciences, the University of Hong Kong, and the University ...
