Greene's most significant contribution to string theory is his application of [[Calabi-Yau]] manifolds to string theory's extra dimensions. According to Greene, these manifolds describe the shape of the extra dimensions.

When string theory's extra dimensions take on the form of Calabi-Yau manifolds, three dimensional physics experiences a phenomenon called [[supersymmetry]].
When string theory's extra dimensions take on the form of Calabi-Yau manifolds, the theory retains an important symmetry called "conformal invariance".
