Generic submanifolds of a locally conformal Kaehler manifold-II
International Journal of Mathematics and Mathematical Sciences, 1993 The purpose of this paper is to study generic submanifolds with parallel structures, generic product submanifolds and totally umbilical submanifolds of a locally conformal Kaehler manifold.

Totally umbilical CR-submanifolds of Semi-Riemannian Kaehler manifolds
International Journal of Mathematics and Mathematical Sciences, 1987 We study totally umbilical CR-submanifolds of a Kaehler manifold carrying a semi-Riemannian metric. It is shown that for dimension of the totally real distribution greater than one, these submanifolds are locally decomposable into a complex and a totally

The Berkovits Method for Conformally Invariant Non-linear Sigma-models on G/H
, 2006 We discuss 2-dimmensional non-linear sigma-models on the Kaehler manifold G/H in the first order formalisim. Using the Berkovits method we explicitly construct the G-symmetry currents and primaries, when G/H are irreducible.

Curvature tensors in Kaehler manifolds [PDF]
Transactions of the American Mathematical Society, 1973 Curvature tensors of Kaehler type (or type K) are defined on a hermitian vector space and it has been proved that the real vector space L K ( V ) {\mathcal {L}_K}(V) of curvature tensors of type K on V is isomorphic with the vector ...

Kaehler and para-Kaehler curvature Weyl manifolds
, 2010 We show that the Weyl structure of an almost-Hermitian Weyl manifold of dimension at least 6 is trivial if the associated curvature operator satisfies the Kaehler identity. Similarly if the curvature of an almost para-Hermitian Weyl manifold of dimension at least 6 satisfies the para-Kaehler identity, then the Weyl structure is trivial as well.

Generic warped product sub manifolds in a Kaehler manifold
Filomat, 2008 Let \(\bar M\) be an almost Hermitian manifold with an almost complex structure \(J\), Hermitian metric \(g\) and let \(M\) be a submanifold of \(\bar M\). For each \(x\in M\), let \(D_x=T_xM\cap JT_xM\). If the dimension of \(D_x\) remains the same for each \(x\in M\) and it defines a holomorphic distribution \(D\) on \(M\), then \(M\) is called a ...

Kaehler structures on spin 6-manifolds
, 2017 We show that many spin 6-manifolds have the homotopy type but not the homeomorphism type of a Kaehler manifold. Moreover, for given Betti numbers, there are only finitely many deformation types and hence topological types of smooth complex projectve spin

Quaternion CR-submanifolds of a quaternion Kaehler manifold
International Journal of Mathematics and Mathematical Sciences, 2001 We study the quaternion CR-submanifolds of a quaternion Kaehler manifold. More specifically we study the properties of the canonical structures and the geometry of the canonical foliations by using the Bott connection and the index of a quaternion CR ...

Compact Totally Real Minimal Submanifolds in a Bochner-Kaehler Manifold
Universal Journal of Mathematics and Applications, 2018 In this paper, we establish the following results: Let $M$ be an $% m-$dimensional compact totally real minimal submanifold immersed in a locally symmetric Bochner-Kaehler manifold $\tilde{M}$ with Ricci curvature bounded from below. Then either $M$ is a

Molecular Ecology, Volume 35, Issue 8, April 2026.ABSTRACT Exposure to environmental pollutants can disrupt the gut microbiota, but how pollutants impact natural, seasonal changes in wildlife gut microbiota remains unknown. We quantified how exposure to radionuclides affected temporal changes in the gut microbiota of bank voles (Clethrionomys glareolus) inhabiting the Chornobyl Exclusion Zone (CEZ ...
