Journal of High Energy Physics 8 (August 2000): 050.1029-8479http://nrs.harvard.edu/urn-3:HUL.InstRepos:2770514We investigate the correspondence between existence/stability of BPS states in type II string theory compactified on a Calabi-Yau manifold and BPS solutions of four dimensional N=2 supergravity. Some paradoxes emerge, and we propose a resolution by considering composite configurations. This in turn gives a smooth effective field theory description of decay at marginal stability. We also discuss the connection with 3-pronged strings, the Joyce transition of special Lagrangian submanifolds, and Pi-stability.en-US10.1088/1126-6708/2000/08/050
