本文是《从电子离域视角看蛋白质相互作用的新数学模型（2025）》的续篇，该文将蛋白质分子建模为内部无奇点空洞的三角形环。本文探讨两个问题：（1）如何定义分子的形状（即如何定义内部无奇点空洞的环的形状）；（2）给定的环是否为分子（即环内的空洞是否为奇点）。针对这两个问题，本文分别给出：（1）利用范畴论概念构建的分子形状的定义方程组；（2）利用上同调论概念确定环内空洞是否为奇点的方程。阅读本文无需具备前序论文、范畴论或上同调论的先验知识。
英文摘要
This article is a sequel to ``A novel mathematical model of protein interactions from the perspective of electron delocalization (2025)'', where protein molecules are modelded as loops of triangles with no singular holes inside. Here we consider two questions: (1) How can we define the shape of a molecule? (i.e., how can we define the shape of a loop with no singular holes inside?), and (2) Is the given loop a molecule? (i.e., are the holes within a loop are singular?). These questions are answered by (1) giving a defining system of equations for the shape of a molecule using concepts from category theory, and (2) giving a equation that determines whether holes within a loop are singular using concepts from cohomology theory, respectively. No prior knowledge of the previous paper, category theory, or cohomology theory is required.
