In this talk I will discuss electric magnetic duality of M-theory on TCS G2 manifold via duality with F-theory. We study the geometrization of D3-branes in M-theory. In certain limit N=2 SUSY is restored and we provide evidences that Minahan-Nemeschansky En theory may be realized this way. The SL(2,Z) monodromy of the 3/7-system is dual to a Fourier-Mukai transform of the dual IIA/M-theory geometry in this limit. Away from the limit the N=2 SUSY is partially broken by a D-term.
Self-intro: Jiahua Tian, graduated from Northeastern University, is currently a postdoctoral fellow at ICTP and is moving to KIAS, whose research focuses on string compactification, geometric engineering and quantum field theory.
