DESCRIPTION: Prof. Dr. Karin Baur (Universität Graz) \n    \n  Abstract: \n
   A dimer model can be defined as a quiver with an embedding of it into a c
 ompact oriented surface\, giving rise to a tiling of the surface. Such dime
 r models can also be considered in the case of a surface with boundary. In 
 particular\, we are interested in dimer models arising from alternating str
 and diagrams (Postnikov\, 2006). To such a diagram D we associate a quiver 
 Q(D) with a natural potential W_D. The quiver Q(D) embedded into a disk is 
 a dimer model with boundary. We then show that the algebra associated to th
 e Grassmannian by B. Jensen\, A. King and X. Su can be realized as an idemp
 otent subalgebra of the algebra of Q(D) (under relations from the potential
  W_D). This is joint work with A. King (Bath) and R. Marsh (Leeds). \n    \
