[geometry-ml:00683] IPMU Mathematics and Physics seminar in Kashiwa

[Yuji Sano]

Dear colleagues,

IPMU (the Institute for the Physics and Mathematics of the Universe)
holds Mathematics and Physics seminar
on Thursday, 15:30 -- 17:00 at Kashiwa Campus of the University of Tokyo.
The detail of the seminar is as follows:

IPMU Mathematics and Physics seminar in Kashiwa

Date: 25 (Wed) June, 2008, 13:30 -- 15:00
(NOTICE: This talk will be held on "Wednesday" and will
begin earlier than usual.)

Place: Seminar Room at Prefab. B, Kashiwa Campus, the University of Tokyo.

Speaker: J.Manuel Garcia-Islas (National Autonomous University of Mexico)

Title: Spin foam models of quantum gravity

Abstract: In this talk we give an introduction to the spin
foam models of quantum gravity which are the covariant version
of loop quantum gravtiy(LQG). Spin foam models are mathematically
rigourous and we will show how in particular cases they are related
to topological quantum field theories. We will also describe a recent novel way
introduced by the presenter for the first time
to interpret black hole entropy in these models.

Title: On multiplier ideal sheaves on toric Fano manifolds.

Abstract: In the existence problem of Kahler-Einstein metrics
on compact Kahler manifolds, the case of Fano manifolds is still open.
It is conjectured that the existence of canonical Kahler metrics
including KE metrics
would be equivalent to stability of manifold in the sense of Geometric
Invariant Theory. Multiplier ideal sheaves (MIS) can be considered as a tool
to describe the bubbling off set in the continuity method/Kahler-Ricci flow
and it is expected that MIS would be related to stability of manifolds.
In this talk, I would like to discuss the support of MIS induced from
the continuity method on toric Fano manifolds.
This talk will be based on a part of the joint work with Akito Futaki.
===============================================================

Please notice that the Mathematics and Physics seminar will be held at
"the Prefab" of IPMU.
It is located at the next of the prefab of "Frontier Sciences,
Computational Biology"
(情報生命科学実験棟). Also please notice that the prefab of IPMU wouldn't
appear on maps of Kashiwa campus,
because it is quite new. As for the location of the prefab of Frontier
Sciences, Computational Biology,
you can check from the following maps.
