From frieze patterns to cluster categories
Published 27 Oct 2020 in math.RT and math.CO | (2010.14302v2)
Abstract: Motivated by Conway and Coxeter's combinatorial results concerning frieze patterns, we sketch an introduction to the theory of cluster algebras and cluster categories for acyclic quivers. The goal is to show how these more abstract theories provide a conceptual explanation for phenomena concerning friezes, principally integrality and periodicity.
