DESCRIPTION:Vladimir Fock (Strasbourg)\nWe will present an elementary con
 structon of a class of\nintegrable systems belonging to A.B. Goncharov and
  R.Kenyon. These are\nnonlinear Hamltonian systems for which one can easil
 y construct\nsolutions\, (in terms of algebraic curves and theta functions
 )\,\nquantization and a discrete group action. These systems are enumerate
 d\nby conves latice polygons in the plane. The study of these systems give
 s\na unified point of view on many known integrable systems as well as she
 d\nlight on sone apparently unrelated problems\, such as the pentagram map
 \nin projective geometry\, Somos integer sequences\, energy spectrum of\ne
 lectrons on a lattice in a magnetic field (Hofstadter butterfly)\,\npseudo
  hyperelliptic integrals.
