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 ...

On CR-submanifolds of the six-dimensional sphere

International Journal of Mathematics and Mathematical Sciences, 1995
We consider proper CR-submanifolds of the six-dimensional sphere S6. We prove that S6 does not admit compact proper CR-submanifolds with non-negative sectional curvature and integrable holomorphic distribution.

What Is the Ideal Dimension of Law?

Ratio Juris, Volume 37, Issue 3, Page 210-229, September 2024.
Abstract Various authors have claimed that law has an ideal dimension owed to a claim to correctness. Against this thesis, this article argues that there are several ideal dimensions of law, namely, a moral, a legal, and an ontological one. All of them are independent of a claim to correctness.

The convenience yield under commodity financialization

Journal of Futures Markets, Volume 44, Issue 4, Page 631-652, April 2024.
Abstract A number of papers have dealt with commodity financialization finding strong evidence for its existence and its effect on commodity prices and volatility. We chose convenience yield (CY) to study the effect of commodity financialization based on the theory of storage and on the argument that CY resembles a call option.

CR-hypersurfaces of complex projective space

International Journal of Mathematics and Mathematical Sciences, 1994
We consider compact n-dimensional minimal foliate CR-real submanifolds of a complex projective space. We show that these submanifolds are great circles on a 2-dimensional sphere provided that the square of the length of the second fundamental form is ...

Single metabarcoding multiplex captures community‐level freshwater biodiversity and beyond

Environmental DNA, Volume 6, Issue 1, January–February 2024.
We developed a highly multiplexed protocol that combines the early pooling of marker genes that target broad taxonomic groups and taxon‐specific markers in a single tube reaction. This approach dramatically reduces the costs of community‐level biodiversity quantification and lowers the need for input DNA without compromising output quality.

Optimal inequalities involving Casorati curvatures for Riemannian maps to nearly Kaehler manifolds

Journal of Inequalities and Applications
We establish a general inequality and optimal inequalities involving the normalized Casorati curvatures and the generalized normalized Casorati curvatures within the horizontal space of a Riemannian map from a Riemannian manifold to a nearly Kaehler ...

Biharmonic curves along Riemannian submersions

Miskolc Mathematical Notes
The purpose of this paper is to study biharmonic curves along Riemannian submersions. We first consider a Riemannian submersion from a Riemannian manifold onto Riemannian manifold and investigate under what conditions a biharmonic curve on the total ...

CR-hypersurfaces of the six-dimensional sphere

International Journal of Mathematics and Mathematical Sciences, 1994
We proved that there does not exist a proper CR-hypersurface of S6 with parallel second fundamental form. As a result of this we showed that S6 does not admit a proper CR-totally umbilical hypersurface.
