DESCRIPTION:Alternating strand diagrams (as introduced by Postnikov) on th
 e disk have been used in the study of the coordinate ring of the Grassmann
 ian. In particular\,&nbsp\; they give rise to clusters of the Grassmannian
  cluster algebras (Scott) or to cluster-tilting objects of the&nbsp\; Gras
 smannian cluster categories of Jensen-King-Su (Baur-King-Marsh).&nbsp\; On
  the other hand\, orbifolds have also been related to cluster structures a
 s Paquette-Schiffler or Chekhov-Shapiro for a geometric approach. Here we 
 introduce orbifold diagrams and show how to associate quivers with potenti
 als to them.&nbsp\; This is joint work with Andrea Pasquali and Diego Vela
 sco.
