The purpose of this research was to define, construct, and classify periodic weaves as new topological objects. To construct weaves, our approach has been improved using combinatorial arguments and we developed new weaving invariants to classify them using knot theory. In particular, we developed the 'polygonal link methods' which allow one to build and classify weaves using tiling theory. More specifically, given a doubly periodic tiling of the plane and a polygonal link method, by instructing how to cover edges and vertices of the tiling by strands, we introduced a systematic algorithm to predict, distinguish, construct and classify weaving motifs and other entangled structures such as polycatenane and mixed motifs. Then, we started a classification of weaves by their symmetry groups.

本研究的目的是定义，构造和分类周期性编织作为新的拓扑对象。为了构建编织，我们的方法已经改进了使用组合参数，我们开发了新的编织不变量，使用结理论对它们进行分类。特别是，我们开发了“多边形链接方法”，允许使用平铺理论构建和分类编织。更具体地说，给定一个双周期平铺的平面和多边形链接的方法，通过指导如何覆盖的边缘和顶点的平铺链，我们介绍了一个系统的算法来预测，区分，构造和分类编织图案和其他纠缠结构，如polycatenane和混合图案。然后，我们开始按对称群对编织进行分类。
