Decomposition of Euclidean Nearly Kähler submanifolds
arXiv:1505.07561
Abstract
We study the foliation space of complex and invariant (by torsion of intrinsic Hermitian connection) umbilic distribution on an isometric immersion from a nearly Kähler manifold into the Euclidean space. Under suitable conditions this leaf space is nearly Kähler and can be decomposed into a product of this leaf space and a 6-dimensional locally homogeneous nearly Kähler manifold.
