Speaker : Prof. Yuan-Pin Lee (University of Utah) Title : Variations on the theme of quantum Lefschetz hyperplane theorem Time : 2019-01-24 (Thu) 15:00 - 16:00 Place : Auditorium, 6 Floor, Institute of Mathematics (NTU Campus) Abstract: The classical Lefschetz hyperplane theorem gives a deep relation between the topology of an algebraic variety X and the intersection of X with a hyperplane, called a hyperplane section of X. I will explain a way to quantize'' this statement. Namely, to relate the quantum cohomology of X with its hyperplane section. This is based on a joint project with Honglu Fan (ETH Zurich)
