Speaker:方浩(The University of Iowa)Time:Thursday, 10:30 - 11:30June 25, 2026Venue:B627, Shuangqing Complex Building ATitle:Gårding Polynomials and Ideal Structures: Geometry, Convexity, and ApplicationsAbstract:In this talk, we develop a general theory of Gårding polynomials based on the positive ray test, which provides a geometric framework for studying multivariate polynomials through...
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...
