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.
