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.
