We show that many of the recently proposed supersymmetric p-brane solutions of d=10 and d=11 supergravity have the property that they interpolate between Minkowski spacetime and...
We consider slightly non-extremal black 3-branes of type IIB supergravity and\nshow that their Bekenstein-Hawking entropy agrees, up to a mysterious factor,\nwith an entropy der...
In matrix theory the effective action for graviton-graviton scattering is a double expansion in the relative velocity and inverse separation. We discuss the systematics of this ...
We show that Dirichlet-branes, extended objects defined by mixed Dirichlet-Neumann boundary conditions in string theory, break half of the supersymmetries of the type~II superst...
We show that the four-dimensional extreme dilaton black hole with dilaton\ncoupling constant $a= \\sqrt{p/(p+2)}$ can be interpreted as a {\\it completely\nnon-singular}, non-di...
