Growth of infinite frieze patterns of affine type
Karin Baur, Anna Felikson, Deepanshu Prasad +2
We analyse the growth coefficients of infinite frieze patterns arising from cluster algebras using cluster modular groups and cluster categories. For a fixed cluster category of af…

Global dimensions of local geodesic ghor algebras
Karin Baur, Charlie Beil
A ghor algebra is a path algebra with relations of a dimer quiver in a compact surface. We show that the global dimension of any cyclic localization of a geodesic ghor algebra on a…

A geometric model for the module category of a string algebra
Karin Baur, Raquel Coelho Simoes
In this paper, we give a geometric construction of string algebras and of their module categories. Our approach uses dissections of punctured Riemann surfaces with extra data at ma…
