Abstract :
We obtain various solutions for D=4 dipoles and their bound states whose U(1) fields originate from various form fields in the effective string theories. We oxidize such dipole solutions to D=10 to obtain delocalized supergravity solutions for the brane/anti-brane pairs and their bound states. We speculate on generalized harmonic superposition rules for supergravity solutions for (intersecting) brane/anti-brane pairs.
