A super Lie 2-algebra extension of the super Poincare Lie algebra in for supersymmetry (as in type II supergravity).
The Chevalley-Eilenberg algebra of the (defining it) is that of the super Poincaré Lie algebra generated from with one further generator in degree 2 and differential given schematically by
This is (CAIB 99, equation (6.3)) for type IIA with and in (Sakaguchi 99 (2.4) and (2.25)) for type IIB with .
It also makes sense to write and for these. See also at string Lie 2-algebra.
The cocycles of the exceptional ∞-Lie algebra cohomology of induce the Green-Schwarz action functional infinity-Wess-Zumino-Witten theory-terms for the D-branes of type II superstring theory (CAIB 99, section 6.1 for IIA and (Sakaguchi 99, section 2) for IIB):

Furthermore, there exists a more general classification of possible supermembranes in spacetime with spatial dimensions and time dimensions, appearing in (Blencowe-Duff 88). In this sense, the brane scan is but the branch of the brane molecule. The objects appearing here are expected to be related to other generalizations of string theory. See D=12 supergravity and bosonic M-theory.
