Abstract:


In 1993, Bershadsky, Cecotti, Ooguri and Vafa predicted a  Feynman structure governing the topological string theory of a compact Calabi Yau threefold. In 2006 Yamaguchi and Yau made the BCOV prediction for quintic threefold more explicit, and deduce structural relations from it.


In 2018 both predictions were verified for quintic's Gromov Witten theory via the study of Mixed Spin P (MSP) fields. In this talk I will explain why MSP theory is natural and then report on recent progress in its further applications.

  • From condensed matter theory to sub-wavelength physics

    Abstract:The ability to manipulate and control waves at scales much smaller than their wavelengths is revolutionizing nanotechnology. The speaker will present a mathematical framework for this emerging field of physics and elucidate its duality with condensed matter theory.About SpeakerHabib Ammari is a Professor of Applied Mathematics at ETH Zürich.
