Title: Wrapped M theory Revisited
Abstract: A complete understanding of M theory remains elusive. In this talk, I revisit a particular limit known as the wrapped membrane theory. It is defined as the zero Planck length limit with a critically tuned three-form and retains some of the stringy nature of the theory. I will present the underlying background structure and extend it by including supersymmetry. This will lead me to present a new supergravity multiplet in eleven dimensions. Contrary to the usual multiplet, it is manifestly non-Lorentzian. Finally, I will use the structure of this supergravity to conjecture dualities to other limits of M theory.
