摘要: We first review standard results of the compactification type IIA and IIB supergravities on a Calabi-Yau threefold illustrate mirror symmetry. Then we compactify same theories class generalized manifolds called Half-flat. obtain scalar potential, show that Half-flat manifold is symmetric to with electric NS-fluxes turned on. In last part, compute full equations motion for N=4 supergravity in central charge superspace graviphotons identified as components vielbein. equivalence formulation components.
