An application of the theory of FI-algebras to graph configuration spaces

Recent work of An, Drummond-Cole, and Knudsen, as well as the author, has shown that the homology groups of configuration spaces of graphs can be equipped with the structure of a finitely generated graded module over a polynomial ring. In this work we study this module structure in certain families of graphs using the language of FI-algebras recently explored by Nagel and R"omer. As an application we prove that the syzygies of the modules in these families exhibit a range of stable behaviors.
