Intersecting M-branes and bound states

In this paper, we construct multi-scalar, multi-center p-brane solutions in toroidally compactified M-theory. We use these solutions to show that all supersymmetric p-branes can be viewed as bound states of certain basic building blocks, namely p-branes that preserve 1/2 of the supersymmetry. We also explore the M-theory interpretation of p-branes in lower dimensions. We show that all the supersymmetric p-branes can be viewed as intersections of M-branes or boosted M-branes in D = 11.
