AbstractTheory of quantum multiplication and Gromov-Witten invariants of a smoothprojective algebraic variety X deals with enumerative questions concerningcurves in X. A long time ago physicists E. Witten, R. Dijkgraaf, E. Verlinde, andH. Verlinde discovered a remarkable system of non-linear differential equations on the generating series for Gromov-Witten invariants. In particular, onecan calc...
报告摘要：The notion of polar foliations is a generalization of the concept of polar actions on Riemannian manifolds. In space forms, polar foliations coincide with isoparametric foliations. In general Riemannian manifolds, these two notions are different from each other. This talk will focus on polar foliations in simply connected symmetric spaces with nonnegative curvature. I will describe re...
