...ld M with nontrivial complex structure moduli yields an N = 2 supergravity theory in D = 5 with a set of scalar fields and their supersymmetric partners all together known as the hypermultiplets (see =-=[15]-=- for a review and additional references). It should be noted that the other matter sector in the theory; the vector multiplets, trivially decouples from the hypermultiplets and can be simply set to ze...

...ld M with nontrivial complex structure moduli yields an N = 2 supergravity theory in D = 5 with a set of scalar fields and their supersymmetric partners all together known as the hypermultiplets (See =-=[16]-=- for a review and additional references). These are partially comprised of the universal hypermultiplet( a, σ, ζ0, ζ̃0 ) , so called because it appears irrespective of the detailed structure of the Ca...

...y, the modified Friedmann equations are derived and the full solution is summarized in section (V). II Five dimensional N = 2 supergravity The dimensional reduction of D = 11 supergravity theory (see =-=[17]-=- for a review) over a rigid Calabi-Yau 3-fold (constant Kähler and complex structure moduli) yields an ungauged N = 2 supersymmetric gravity theory in D = 5 with a matter sector comprised of four sca...

...hey are written in split-complex form. Specifically, these have the interpretation of instantons and 3-branes in D = 5. 2 2 Complex and split-complex N = 2 supergravity The dimensional reduction (see =-=[19]-=- for a review) of D = 11 supergravity theory over a rigid Calabi-Yau 3-fold with constant Kähler and complex structure moduli yields an ungauged N = 2 supersymmetric gravity theory in D = 5 with a ma...
