Functoriality of real crossed product K-theory spectral sequences with respect to group homomorphisms
Jeffrey L. Boersema, Sarah L. Browne, Elizabeth Gillaspy +1
Spectral sequences are a key tool for computing the K-theory of a crossed product C-algebra. However, the impact of a group homomorphism on such a spectral s…

Relating insplittings of 2-graphs and of textile systems
Samantha Brooker, Priyanga Ganesan, Elizabeth Gillaspy +3
The graphical operation of insplitting is key to understanding conjugacy of shifts of finite type (SFTs) in both one and two dimensions. In this paper, we consider two approaches t…

Products, crossed products, and Zappa--Szép products for -graphs
Adlin Abell-Ball, Elizabeth Gillaspy, George Glidden-Handgis +1
We use the lens of Zappa--Szép decomposition to examine the relationship between directed graph products and -graph products. There are many examples of higher-rank graphs, or…
