Dear colleagues,

I am announcing the following seminar at IPMU
(the Institute for the Physics and Mathematics of the Universe)
on next Monday (13:30--15:00 and 15:30--17:00).

ps. I am sorry for late announcement.

Best Regards,
Yuji Sano (IPMU)

IPMU MS seminar in Kashiwa
===============================================================
Date:  	October 27, 2008, 13:30 - 15:00
Place: 	Seminar Room at IPMU Prefab. B, Kashiwa Campus of the
University of Tokyo

Speaker: 	Michael Semenov-Tian-Shansky (University of Bourgogne)

Title: 	Poisson groups and differential Galois theory of Schroedinger
equation on the circle.

Abstract: 	The projective geometry approach to Schroedinger equations
on the circle and
the differential Galois theory are combined with the theory of Poisson
Lie groups to construct
 a natural Poisson structure on the space of wave functions of the
Schroedinger equation on
 the circle (at the zero energy level). Applications to KdV-like
nonlinear equations are discussed.
The same approach may be applied to second order difference operators
on a one-dimensional
 lattice, yielding an extension of the lattice Poisson Virasoro algebra.

Unified cohomology
