On concircular curvature tensor in a Lorentzian α-Sasakian manifold with respect to the quarter-symmetric non-metric connection

Acta et Commentationes Universitatis Tartuensis de Mathematica, 2019
In the present paper, some properties of concircular curvature tensor in a Lorentzian α-Sasakian manifold with respect to the quarter-symmetric non-metric connection have been studied.

A General Type of Almost Contact Manifolds [PDF]

Among almost contact manifolds Sasakian manifolds, Kenmotsu manifolds (called also “a certain class of almost contact manifolds”) and cosymplectic manifolds have been studied by many authors.

Invariant Submanifolds of Generalized Sasakian-Space-Forms

, 2019
The object of this paper is to study the invariant submanifolds of generalized Sasakian-space-forms. Here, we obtain some equivalent conditions for an invariant submanifold of a generalized Sasakian-space-forms to be totally geodesic.Comment: 11 ...

Orthogonal nets and Clifford algebras

, 1998
A Clifford algebra model for M"obius geometry is presented. The notion of Ribaucour pairs of orthogonal systems in arbitrary dimensions is introduced, and the structure equations for adapted frames are derived.

Concircular curvature tensor of nearly cosymplectic manifolds in terms of the generalized Tanaka-Webster connection

Filomat
In this paper, we study concircular curvature tensor of nearly cosymplectic manifolds in terms of the generalized Tanaka-Webster connection and then, we emphasized the properties that concircular curvature tensor of nearly cosymplectic manifolds in terms of the generalized Tanaka-Webster connection provides in case of flatness, ?-concircularly flatness,

A study of the concircular curvature tensor and its interactions with other tensors under the Lie derivative in \(GBK- 5RF_n\)

University of Aden Journal of Natural and Applied Sciences
This research paper delves into a comprehensive analysis of the concircular curvature tensor and its intricate relationships with other tensors under the Lie derivative. The concircular curvature tensor, a fundamental geometric invariant, plays a pivotal role in characterizing the local geometry of Riemannian manifolds.

On P-Sasakian manifolds satisfying certain conditions on the concircular curvature tensor

, 2007
We classify P-Sasakian manifolds, which satisfy the conditions Z(xi,X). Z = 0, Z(xi, X) . R = 0, R(xi, X) . Z = 0, Z(xi, X) . S = 0 and Z(xi, X) . C = 0.

Variational problems of normal curvature tensor and concircular scalarfields

Variational problems of normal curvature tensor and concircular scalarfields
We consider the integral of (the square of) the length of the normal curvature tensor for immersions of manifolds into real space forms, especially into spheres. The first variation formula is given and the Euler-Lagrange equation is expressed in terms of the isothermal coordinates when the submanifold is two-dimensional.
