The Graph Minor Theorem of Robertson and Seymour is one of the most celebrated results in the history of combinatorics, spanning decades (and hundreds of pages) of work. In this note we discuss recent work of Miyata, Proudfoot, and the author that proposes a framework that would allow one to apply the Graph Minor Theorem to algebra and topology, building on seminal contributions by Sam and Snowden. Though the capstone of this framework is still only conjectural (See Conjecture 2.3), a weaker version (See Theorem 2.4) of the capstone has been proven and already has far ranging consequences in topological combinatorics and algebra. Specifically, we will discuss applications of this framework to the study of matching complexes and configuration spaces of graphs.To begin, let’s standardize terminology by defining a graph to be a (non-empty) finite, connected, at most one-dimensional CW-complex. If one prefers to think about graphs
