An Introduction to $G_2$ / $Spin(7)$ Geometry and M-Theory / F-Theory Compactifications

2025/10/22 (Wed.) 14:00~15:00
  • Date : 2025/10/22 (Wed.) 14:00~15:00
  • Location : Room 515, Cosmology Building, NTU
  • Speaker : Tathagata Ghosh (NCTS)
  • Organizer : Wille Liu (AS), Harry Richman (NCTS)
  • Abstract : Aimed at differential geometers, algebraic geometers, and theoretical physicists, in this very elementary and self-contained talk, I will discuss various geometric and physical notions related to manifolds with special holonomy. I will discuss the concept of holonomy; some spin geometry including notions of spinors and Dirac operators; supersymmetry; Calabi--Yau, $G_2$ and $Spin(7)$ manifolds, and some algebraic/analytic constructions. Finally, I will connect all these notions in the context of string theory/M theory/F theory compactifications.
