SUMMARY:Variational principles for discrete maps - Martin Tassy (UCLA)
DTSTART:20170502T140000Z
DTEND:20170502T150000Z
UID:TALK72414@talks.cam.ac.uk
CONTACT:Perla Sousi
DESCRIPTION:Previous works have shown that arctic circle phenomenons and l
 imiting behaviors of some integrable discrete systems can be explained by 
 a variational principle. In this talk we will present the first results of
  the same type for a non-integrable discrete system: graph homomorphisms f
 orm Z^d to a regular tree. We will also explain how the technique used cou
 ld be applied to other non-integrable models.
