Examples of geodesic ghor algebras on hyperbolic surfaces
Karin Baur, Charlie Beil
Cancellative dimer algebras on a torus have many nice algebraic and homological properties. However, these nice properties disappear for dimer algebras on higher genus surfaces. We…

Frieze patterns of integers
Karin Baur
The famous theorem of Conway and Coxeter on frieze patterns gave a geometric interpretation to integral friezes via triangulations of polygons. In this article, we review this resu…

A generalization of cancellative dimer algebras to hyperbolic surfaces
Karin Baur, Charlie Beil
We study a new class of quiver algebras on surfaces, called 'geodesic ghor algebras'. These algebras generalize cancellative dimer algebras on a torus to higher genus surfaces, whe…
