Abstract: We present a version of ten-dimensional IIA supergravity containing a 9-form potential for which the field equations are equivalent to those of the standard, massless, IIA theory for vanishing 10-form field strength, F 10 , and to those of the ‘massive’ IIA theory for non-vanishing F 10 . We present a multi 8-brane solution of these equations that generalizes the 8-brane of Polchinski and Witten. We show that this solution is T -dual to a new multi 7-brane solution of S 1 compactified IIIB supergravity, and that the latter is T -dual to the IIA 6-brane. When combined with the Sl(2; Z ) U -duality of the type-IIB superstring, the T -duality between type-11 7-branes and 8-branes implies a quantization of the cosmological constant of type-IIA superstring theory. These results are made possible by the construction of a new massive N = 2 D = 9 supergravity theory. We also discuss the 11-dimensional interpretation of these type-II p -branes.
