Abstract
The original membrane at the end of the universe corresponds to a probe M2-brane of signature occupying the boundary of the spacetime , and is described by an SCFT. However, it was subsequently generalized to other worldvolume signatures and other spacetime signatures . An interesting special case is provided by the brane at the end of the de Sitter universe which has recently featured in the dS/CFT correspondence. The resulting CFT contains the one recently proposed as the holographic dual of a four-dimensional de Sitter cosmology. Supersymmetry restricts S, T, s, t by requiring that the corresponding bosonic symmetry be a subgroup of a superconformal group. The case of is ‘doubly holographic’ and may be regarded as the near horizon geometry of M2-branes or equivalently, under interchange of conformal and R-symmetry, of M5-branes, provided . The same correspondence holds in the pp-wave limit of conventional M-theory.
