DESCRIPTION:Speaker: Valentina Disarlo (University of Manchester)\n\nTitl
 e: The geometry of the saddle connection graph\n\nAbstract: For a half-t
 ranslation surface\, its saddle connection graph has saddle connections 
 as vertices\, and edges connecting pairs of non-crossing saddle connecti
 ons. It can be seen as a subgraph of the arc graph of the underlying top
 ological surface. In this talk\, I will discuss both the fine and large-
 scale geometry of the saddle connection graph. We show that any isomorph
 ism between two such graphs is induced by an affine diffeomorphism betwe
 en the underlying translation surfaces. However\, the situation is compl
 etely different when one considers the quasi-isometry type: all saddle c
 onnection graphs are quasi-isometric. We will also discuss a characteriz
 ation of its Gromov boundary. This is based on joint work with Robert Ta
 ng\, Huiping Pan\, and Anja Randecker.\n\nRoom: Frank Adams 1\n\nFurther
