BornInfeld particles and Dirichlet pbranes
Abstract
BornInfeld theory admits finite energy point particle solutions with δfunction sources, Blons. I discuss their role in the theory of Dirichlet pbranes as the ends of strings intersecting the brane when the effects of gravity are ignored. There are also topologically nontrivial electrically neutral catenoidal solutions looking like two pbranes joined by a throat. The general solution is a nonsingular deformation of the catenoid if the charge is not too large and a singular deformation of the BIon solution for charges above that limit. The intermediate solution of BPS and Coulomblike. Performing a duality rotation we obtain monopole solutions, the BPS limit being a solution of the abelian Bogolmol'nyi equations. The situation closely resembles that of sub and super extreme blackbrane solutions of the supergravity theories. I also show that certain special Lagrangian submanifolds of C^{p}, p = 3, 4, 5, may be regarded as supersymmetric configurations consisting of pbranes at angles joined by throats which are the sources of global monopoles. Vortex solutions are also exhibited.
