Abstract: Hom shifts form a class of multidimensional shifts of finite type (SFT) and consist of colorings of the grid Z^2 where adjacent colors must be neighbors in a fixed finite undirected simple graph G. The gluing gap measures how far any two square patterns of size n can be glued. In this talk I will focus on possible values of gluing gap and algebraic properties of objects related to this problem. I will also comment on algorithmic complexity of possible solutions. (Based on joint work(s) with Nishant Chandgotia, Silvere Gangloff and Benjamin Hellouin de Menibus.)
