Query: D-Brane Dynamics in Dp-Brane Background   By using Dirac-Born-Infeld action we study the real time dynamics of D-branes
in the vicinity of a stack of Dp-branes where the role of the tachyon of the
open string models is played by the radial mode on the D-branes. We examine the
behaviour of the tachyon potential and study the hamiltonian formulation and
classical solutions of such systems. We also study the homogeneous solutions of
the classical equations of motion in these cases.
