A GENERALIZED VIRASORO ALGEBRA FOR THE TYPE-IIA SUPERSTRING Academic Article

abstract

• We extend Siegel's generalised Virasoro algebra for type I superstrings to type IIA superstrings. Since the type IIA superstring can be obtained from the eleven-dimensional supermembrane by dimensional reduction, it is natural to seek a type IIA Virasoro algebra that can be derived from one for the supermembrane. This leads to an algebra containing an infinite number of generators, including as a subset those of the direct sum of a left-moving and a right-moving type I algebra. We also find a remarkable property of the Ka-Moody algebra for supermembranes and type IIA superstrings which is likely to play an important role in finding the superspace constraints for d=11, N=1 and d=10, N=2a supergravity theories, by a generalisation of the notion of integrability along light-like lines. 1989.
