[Satoshi Kondo]

Dear colleagues:

We announce the following seminar at IPMU
(the Institute for the Physics and Mathematics of the Universe).

Regards,

Satoshi Kondo (IPMU)

===============================================================
Date:  	February 19, 2009, 15:30-17:00
Place: 	Seminar Room at IPMU Prefab. B, Kashiwa Campus of the
University of Tokyo
Speaker: 	Shouhei Ma (University of Tokyo)
Title: 	0-dimensional cusps of the Kahler moduli of a K3 surface
Abstract: For a K3 surface, it is well-known that its Kahler moduli
admits the Baily-Borel compactification. The central topic of my talk
is that the 0-dimensional cusps of the Kahler moduli are in one-to-one
correspondence with the twisted Fourier-Mukai partners of the K3
surface. This correspondence leads to a counting formula for the
0-dimensional cusps of Kahler moduli. When the Picard number of the K3
surface is 1, the correspondence can be described explicitly by using
classical theory of elliptic modular curve. I will begin by recalling
the notions of Fourier-Mukai partner and twisted Fourier-Mukai
partner.

Please notice that the seminar will be held at the "Prefab" of IPMU.
