We consider a brane moving close to a large number of coincident branes. We compare the calculation of the effective action using the gauge theory living on the brane and the calculation using the supergravity approximation. We discuss some general features about the correspondence between large N gauge theories and black holes. Then we do a one loop calculation which applies for extremal and n...

We argue that black p-branes will occur in the collision of D0-branes at Planckian energies. This extents the Amati, Ciafaloni and Veneziano and 't Hooft conjecture that black holes occur in the collision of two light particles at Planckian energies. We discuss a possible scenario for such a process by using colliding plane gravitational waves. D-branes in the presence of black holes are discus...

Unlike the Schwarzschild black string in the Randall-Sundrum scenario which is known to have the geodesics reaching the AdS-horizon terminating there, the D=7 extremal BPS selfdual string of N = 2 gauged supergravity potentially differs from this result. I give a complete proof that timelike radial trajectories of the selfdual string solution that escapes to r = ∞ do not see a curvature singula...
