DESCRIPTION:Speaker: Professor Pavel Tumarkin (Durham)\n\nTitle: The Fare
 y graph and ideal tetrahedra\n\nAbstract: We explore a 3-dimensional cou
 nterpart of the Farey tessellation and show that it inherits many proper
 ties of the usual 2-dimensional Farey graph. In particular\, we get a cl
 assification of SL_2-tilings over Eisenstein integers in terms of pairs 
 of paths on the graph. We also get a 3-dimensional counterpart of the Pt
 olemy relation. The talk is based on a joint work with Anna Felikson\, O
 leg Karpenkov and Khrystyna Serhiyenko.
