superpotentials for d-branes and a-infinity algebras
abstract:
worldvolumes of $d$-branes on calabi-yau threefolds give rise to supersymmetric gauge theories. if the $d$-brane is marginally stable these theories are quiver gauge theories. using the derived category of coherent sheaves to analyze such $d$-branes, the superpotential of these gauge theories may be determined systematically.
