Description
In this talk, I revisit the wrapped membrane sector of M theory. It is defined as the zero Planck length limit with a critically tuned three-form and decouples the wrapping modes from the rest of the spectrum. I will present the underlying background geometry and extend it by including supersymmetry. This will lead me to introduce a new supergravity multiplet in eleven dimensions. Contrary to the usual multiplet, it is manifestly non-Lorentzian. Finally, I will conjecture dualities to other limits of M theory.
