这是一篇未经参考的讲义,基于 2019 年 1 月 21--24 日高丽大学“离散微分几何入门研讨会”的讲座。在本讲义中,我们讨论拓扑晶体学,这是一种晶体结构的数学理论。图的所有位置中最对称的结构是通过拓扑晶体学中的变分原理获得的。我们还讨论了 3 维欧几里得空间中的三价离散表面理论,这是晶体/分子结构的数学模型。
This is an unrefereed lecture note based on lectures in 'Introductory Workshop on Discrete Differential Geometry' at Korea University on January 21--24, 2019. In this note, we discuss topological crystallography, which is a mathematical theory of crystal structures. The most symmetric structure among all placements of the graph is obtained by a variational principle in topological crystallography. We also discuss a theory of trivalent discrete surfaces in $3$-dimensional Euclidean space, which are mathematical models of crystal/molecular structures.
