DESCRIPTION:Ben Lees (University of Leeds) will speak at the Probability 
 seminar.\n\nTitle: Discrete lattice models as complex spin systems\n\nAb
 stract: It has long been known that some important spin systems on latti
 ces\, such as the spin-O(N) model\, have representations in terms of dis
 crete structures (loops\, paths etc) on the lattice. This has been a fru
 itful connection\, however many discrete models on lattices\, such as pe
 rcolation\, the dimer model\,  spatial random permutations\, and others\
 , are also of considerable interest. In these cases there was no precise
  link to spin systems\, either because the motivation came from elsewher
 e\, or because these are toy models of such systems that have since take
 n on a life of their own. In this talk I will present a spin system wher
 e spins take continuous complex values. By choosing the measures appropr
 iately\, virtually any discrete system of interest can be obtained as a 
 special case. These spin systems then lend themselves naturally to sever
 al of the well developed tools of classical spin systems.\nThis is joint
  work with Volker Betz.
