SUMMARY:Yunhyung Cho\, Monotone Lagrangian Tori in Fano Varieties
DESCRIPTION:     Speaker\n\n\nYunhyung Cho\nSungkyunkwan University\n\n\n\n\n\n\nThis is a survey talk of current progress of mirror symmetry of Fano varieties. For a given smooth Fano variety X\, it has been conjectured that there exists a Laurent polynomial called a (weak) Landau-Ginzburg mirror (or weak LG mirror shortly) which encodes a quantum cohomology ring structure of X. Tonkonog proved that one can find a weak LG mirror using a monotone Lagrangian torus in X. In this talk I will explain how to find a monotone Lagrangian torus using a Fano toric degeneration of X. If time permits\, I will also describe a monotone Lagrangian torus in a given flag variety.

SUMMARY:Donghoon Jang\, Circle Actions on Almost Complex Manifolds with Isolated Fixed Points
DESCRIPTION:     Speaker\n\n\nDonghoon Jang\nPusan National University\n\n\n\n\n\n\nWe briefly review group actions on manifolds and equivariant cohomology\, which is cohomology of a manifold with a group action. We review classification results for circle actions on various types of manifolds in low dimensions. An almost complex manifold is a manifold with a complex structure on its tangent bundle; every complex or symplectic manifold is almost complex. For an action of the circle group on a compact almost complex manifold that has isolated fixed points\, we study its properties and discuss the classification when the number of fixed points is small.

SUMMARY:Insong Choe\, Subsheaves of Maximal Rank in a Symplectic and Orthogonal Bundle over a Curve
DESCRIPTION:    Speaker\n\n\nInsong Choe\nKunkuk University\n\n\n\n\n\n\nWe first review the known results on the Quot schemes on a smooth algebraic curve. Next we explain how they can be generalized to the Lagrangian Quot scheme\, which parametrizes Lagrangian subsheaves on a symplectic vector bundle. Also we discuss the parallel results for orthogonal bundles. This will be an overview of the findings over the past 15 years in collaboration with George H. Hitching and D. Cheong.
