摘要

图论和矩阵理论相互关联，矩阵为概括和分析图的结构和独立性提供了一种方法。链定理是矩阵和图论中的重要工具，可以分析与图相关的矩阵结构。Chun、Mayhew 和 Oxley [2] 的一项重大贡献是建立了内部 4 连接二元矩阵的链定理，阐明了其中的操作。我们的研究在此基础上将矩阵结果具体化为内部 4 连接的图。我们研究的主要目标是将这个矩阵的链式定理完善为内部 4 连接图的链式定理，使对矩阵理论不太熟悉的人更容易理解。

Refining a chain theorem from matroids to internally 4-connected graphs

Graph theory and matroid theory are interconnected with matroids providing a way to generalize and analyze the structural and independence properties within graphs. Chain theorems, vital tools in both matroid and graph theory, enable the analysis of matroid structures associated with graphs. In a significant contribution, Chun, Mayhew, and Oxley [2] established a chain theorem for internally 4-connected binary matroids, clarifying the operations involved. Our research builds upon this by specifying the matroid result to internally 4-connected graphs. The primary goal of our research is to refine this chain theorem for matroids into a chain theorem for internally 4-connected graphs, making it more accessible to individuals less acquainted with matroid theory.
