In 1987 two versions of the branescan of Ddimensional super pbranes were put forward. The first pinpointed those (p, D) slots consistent with kappasymmetric GreenSchwarz type actions; the second generalized the membrane at the end of the universe idea to all those superconformal groups describing pbranes on the boundary of AdSp+2 ×S D−p−2. Although the second version predicted D3 and M5 branes in addition to those of the first, it came unstuck because the 1/2 BPS solitonic branes failed to exhibit the required symmetry enhancement in the nearhorizon limit, except in the nondilatonic cases (p = 2, D = 11), (p = 3, D = 10) and (p = 5, D = 11). Just recently, however, it has been argued that the fundamental D = 10 heterotic string does indeed display a nearhorizon enhancement to OSp(82) as predicted by the branescan, provided α ′ corrections are taken into account. If this logic could be extended to the other strings and branes, it would resolve this 21yearold paradox and provide a wealth of new AdS/CFT dualities, which we tabulate.

Abstract: We analyze the AdS3 × M7 type supersymmetric solutions, including nontrivial fluxes, of the Killing spinor equations in the heterotic supergravity. We classify these solutions by their Gstructures and intrinsic torsions, for the cases that the number of sevendimensional Killing spinors N are equal to 1, 2, 3 and 4. We find that the solutions cannot have nontrivial warp factor and the seven dimensional manifold M7 is charactrized by G2(SU(3))structures for N = 1 (2) case and SU(2)structure for N = 3 and 4 cases. They are further classified by their nontrivial intrinsic torsions. It is shown, including the leading order α ′corrections, that if we impose the Bianchi identities, the integrability conditions of the Killing spinor equations imply all the field equations. – 1 –
