摘要：

We construct a geometric model of eight-dimensional manifolds and realize them in the context of type II string theory. These eight-manifolds are constructed by non-trivial T-4 fibrations over Calabi-Yau two-folds. These give rise to eight-dimensional non-Kahler Hermitian manifolds with SU (4) structure. The eight-manifold is also a circle fibration over a seven-dimensional G(2) manifold with skew torsion. The eight-manifolds of this type appear as internal manifolds with SU (4) structure in type IIB string theory with F-3 and F-7 fluxes. These manifolds have generalized calibrated cycles in the presence of fluxes. (C) 2016 The Author(s). Published by Elsevier B.V.
