Quasi-Statistical Manifolds with Almost Hermitian and Almost Anti-Hermitian Structures
Let (M, g, ∇) be a 2n-dimensional quasi-statistical manifold that admits a pseudo-Riemannian metric g (or h) and a linear connection ∇ with torsion. This paper aims to study an almost Hermitian structure (g, J ) and an almost anti-Hermitian structure (h,

NOTES ON CRITICAL ALMOST HERMITIAN STRUCTURES [PDF]
We discuss the critical points of the functional F‚,µ(J,g) = R M (‚?+µ? ⁄ )dvg on the spaces of all almost Hermitian structures AH(M) with (‚,µ) 2 R 2 i (0,0), where ? and ? ⁄ being the scalar curvature and the ⁄-scalar curvature of (J,g), respectively.

Chern-flat and Ricci-flat invariant almost Hermitian structures
Let \((M, g, J)\) be an almost Hermitian manifold and \(\nabla \) its Chern connection, which in the quasi-Kähler case coincides with the so-called second canonical Hermitian connection. Let \(R\) be the curvature tensor and \(\text{Ric}(J)(X, Y):=\frac{1}{2}Tr_{\omega }R(X, Y, \cdot, \cdot )\) be the Ricci form of \(\nabla \), where \(\omega \) is the

Almost Kaehlerian and Hermitian Structures on Four Dimensional Indecomposable Lie Algebras
It is known that from a given almost Hermitian structure on a simply connected Liegroup, one can obtain left-invariant almost Hermitian structure on its Lie algebra.In this work, we consider Mubarakzyanov’s classification of four-dimensional realLie ...

On nearly Kählerian manifolds and quasi-Sasakian hypersurfaces axiom
It is known that an almost contact metric structure is induced on an arbitrary hypersurface of an almost Hermitian manifold. The case when the almost Hermitian manifold is nearly Kählerian and the almost contact metric structure on its hypersurface is ...

On stability of Hermitian structures on 6-dimensional planar submanifolds of Cayley algebra
We consider 6-dimensional planar submanifolds of Cayley algebra. As it is known, the so-called Brown — Gray three-fold vector cross products induce almost Hermitian structures on such submanifolds. We select the case when the almost Hermitian structures

Nearly Sasakian Manifolds of Constant Type
The article deals with nearly Sasakian manifolds of a constant type. It is proved that the almost Hermitian structure induced on the integral manifolds of the maximum dimension of the first fundamental distribution of the nearly Sasakian manifold is a ...
