Ricci Curvature Inequalities for Skew CR-Warped Product Submanifolds in Complex Space Forms

open access: yesMathematics, 2020
The fundamental goal of this study was to achieve the Ricci curvature inequalities for a skew CR-warped product (SCR W-P) submanifold isometrically immersed in a complex space form (CSF) in the expressions of the squared norm of mean curvature vector and

Parallel submanifolds of complex space forms II [PDF]

open access: yesNagoya Mathematical Journal, 1983
This is a continuation of Part I, which appeared in this journal.In the previous paper I we have defined the following notions: orthogonal Jordan triple system (OJTS), orthogonal symmetric graded Lie algebra (OSGLA), orthogonal Jordan algebra (OJA), Hermitian symmetric graded Lie algebra (HSGLA).

Product complex submanifolds on of indefinite complex space forms

open access: yesRocky Mountain Journal of Mathematics, 1988
An analogue of the Segre imbedding for the indefinite complex projective (and hyperbolic) space is constructed. The paper then deals with isometric holomorphic immersions of a product of two complete indefinite Kähler manifolds into a complex projective space.

Chen-Ricci Inequalities with a Quarter Symmetric Connection in Generalized Space Forms

open access: yesAdvances in Mathematical Physics, 2021
In this article, we obtain improved Chen-Ricci inequalities for submanifolds of generalized space forms with quarter-symmetric metric connection, with the help of which we completely characterized the Lagrangian submanifold in generalized complex space ...

Second order parallel tensor in real and complex space forms

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
Levy's theorem ‘A second order parallel symmetric non-singular tensor in a real space form is proportional to the metric tensor’ has been generalized by showing that it holds even if one assumes the second order tensor to be parallel (not necessarily ...

Oriented vehicles travelling in spherical space [PDF]

open access: yes, 2009
This paper tackles the path planning problem for oriented vehicles travelling in the non-Euclidean 3-Dimensional space; spherical space S3 . For such problem the orientation of the vehicle is naturally represented by orthonormal frame bundle; the ...

Biharmonic and Quasi-Biharmonic Slant Surfaces in Lorentzian Complex Space Forms

open access: yesAbstract and Applied Analysis, 2013
In 1991, Chen and Ishikawa initially studied biharmonic marginally trapped surfaces in neutral pseudo-Euclidean 4-space. Recently, biharmonic and quasi-biharmonic marginally trapped Lagrangian surfaces in Lorentzian complex space forms were studied by ...
