Block gluing in Hom shifts and path reconfiguration in graphs

-- Benjamin Hellouin de Menibus (LISN, Galac)

summary: We study some tilings spaces that are defined from graph homomorphisms, called Hom shifts. Compared to general tiling spaces, they look the same in every direction (invariance by rotation and symmetry) and many undecidable problems or questions in tiling spaces seem to become easier for these objects, using graph-theoretical ...
