Harmonic morphisms between almost Hermitian manifolds

open access: yes, 1995
We obtain conditions on the Lee form under which a holomorphic map between almost Hermitian manifolds is a harmonic map or morphism. Then we discuss under what conditions (i) the image of a holomorphic map from a cosymplectic manifold is also cosymplectic, (ii) a holomophic map with Hermitian image defines a Hermitian structure on its domain.

Complex submanifolds in almost Hermitian manifolds

open access: yes, 1987
A complex hypersurface M in an almost Hermitian manifold is called a \(\sigma\)-hypersurface if the second fundamental form \(\sigma\) and the almost complex structure J satisfy \(\sigma (X,JY)=\sigma (JX,Y)=J\sigma (X,Y)\) for X, Y tangent to M. The main purpose of this article is to obtain some equivalent conditions for a \(\sigma\)-hypersurface to ...

\(CR\)-submanifolds of almost Hermitian manifolds

open access: yes, 1994
\(CR\)-submanifolds are well studied in the case that \((M,g)\) is a Kähler manifold. In this paper, \((M,g)\), in general, is not Kähler. We examine the case of some classes of almost Hermitian manifolds, which generalize the Kähler case. In particular, the more interesting results are obtained for \(CR\)-submanifolds of quasi-Kähler, semi-Kähler, \({\
