  =============================================================
  We shall have a FMSP-IPMU special seminar as follows.

  Speaker:   Hayato Chiba   (Kyushu university)
   Title:   Painleve equations and weight system
    Date:   Mon, April 20, 2015, 10:00-12:00, 13:30-15:00, 15:30-17:30
    Place:   Balcony A,  IPMU

  Abstract:
  A weight (a tuple of integers) is one of the invariants of the
  Painlev\'{e} equation determined by the Newton diagram of the equation.
  In this talk, several topics about the Painlev\'{e} equations and
  weights will be introduced.

  In the first lecture, a brief review of the Painlev\'{e} equations
  and the analysis of the Painlev\'{e} equations by means of the
  weighted projective spaces associated with the weights will be given.

  In the second lecture, it will be shown that the weights for the
  Painlev\'{e} equations are closely related to Saito's theory of weight
  systems.

  In the third lecture, it will be shown that the hierarchy of the
  Painlev\'{e} equations is obtained from a certain Lie-Poisson
  structure. The weights are recovered through the Darboux
  coordinates of the Poisson structure.
