Query: 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.
