Algebra of Kodaira-Spencer Gravity and Deformation of Calabi-Yau   Manifold
  We study the algebraic structure of the configuration space of the Kodaira-Spencer gravity theory on a Calabi-Yau threefold. We then investigate the deformation problem of the Kodaira-Spencer gravity at the classical level using the algebraic tools obtained here.
