Title: 	Landau-Ginzburg model and integrable hierarchies more
Date: 	May 07, 2009, 15:30 - 17:00
Place: 	Seminar Room at IPMU Prefab. B
Abstract: Almost twenty years ago, the celebrated theorem of
Witten-Kontsevich asserts that the intersection theory of
Deligne-Mumford space is governed by KdV-hierarchies.
Around the same time, Witten proposed a sweeping generalization which
leads to the representation theory of infinite dimensional Lie algebra
and singularity theory/Landau-Ginzburg model. In the talk, we will
sketch the recent resolution of Witten's vision by Fan-Jarvis and
author and the appearance of new phenomenon such as mirror symmetry in
the integrable hierarchy problem.

Title: 	Lecture Series on Topological Strings and
                Mirror Symmetry at Landau-Ginzburg-Orbifolds
Date: 	May 08, 2009, 10:30 - 12:00
                May 11, 2009, 10:30 - 12:00
                May 11, 2009, 13:30 - 15:00
Place: 	Seminar Room at IPMU Prefab. B
Keywords:
* Topological string at LG-orbifold (explaining more detail of our construction
of GW-type invariants at LG-orbifold)
* LG mirror symmetry after Berglund-Hubsch-Krawitz (explaining
a general mirror symmetry construction for LG-orbifold)
* LG/CY-correspondence for quintic 3-fold.
