TL;DR: In this paper, it was shown that the M-theory/IIA and IIA/IIB superstring dualities together with the diffeomorphism invariance of the underlying theories require the presence of certain p-brane bound states in IIA and IIB super string theories preserving 1/2 of the spacetime supersymmetry.
Abstract: We show that the M-theory/IIA and IIA/IIB superstring dualities together with the diffeomorphism invariance of the underlying theories require the presence of certain p-brane bound states in IIA and IIB superstring theories preserving 1/2 of the spacetime supersymmetry. We then confirm the existence of IIA and IIB supergravity solutions having the appropriate p-brane bound states interpretation.

TL;DR: In this paper, the authors presented supersymmetric solutions of D = 11 supergravity obtained by intersecting the brane configuration interpreted as a 2-brane lying within a 5brane, which are boosted along a common string and/or superposed with a Kaluza-Klein monopole.
Abstract: We present new supersymmetric solutions of D=11 supergravity obtained by intersecting the brane configuration interpreted as a 2-brane lying within a 5-brane. Some of these solutions can be boosted along a common string and/or superposed with a Kaluza-Klein monopole. We also present a new embedding of the extreme four dimensional dyonic black hole with finite horizon area. These solutions are a consequence of a rather simple set of rules that allow us to construct the composite M-branes.

TL;DR: In this paper, the authors generalize all the known supersymmetric composite M-branes to the corresponding black configurations, and use simple rules to construct these black branes.
Abstract: We generalise all the known supersymmetric composite M-branes to the corresponding black configurations. Thermodynamical formulae is written by using the simple rules to construct these black branes.
TL;DR: In this article, a class of Kaluza-Klein electrically charged black p-brane solutions of ten-dimensional, type IIA superstring theory are studied in the context of M-theory.
Abstract: We present a class of Kaluza-Klein electrically charged black p-brane solutions of ten-dimensional, type IIA superstring theory. Uplifting to eleven dimensions these solutions are studied in the context of M-theory. They can be interpreted either as a p+1 extended object trapped around the eleventh dimension along which momentum is flowing or as a boost of the following backgrounds: the Schwarzschild black (p+1)-brane or the product of the (10-p)-dimensional Euclidean Schwarzschild manifold with the (p+1)-dimensional Minkowski spacetime.
