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.

Concircular Curvature Tensor’s Properties on Lorentzian Para-Sasakian Manifolds

Springer Proceedings in Mathematics and Statistics, 2020
The objective of the present paper is to study and investigate the geometric properties of Concircular curvature tensor on Lorentzian type para-Sasakian manifold endowed with the quarter-symmetric nonmetric connection. At last, we provide an example which satisfies the conditions of \(\xi _{*}\)-Concircularly flat and \(\phi _{*}\)-Concircularly flat ...

On the \(D\)-concircular curvature tensor of a generalized Sasakian-space-form

2021
Summary: The object of this paper is to study of \(D\)-concircular curvature tensor on generalized Sasakian-space-forms. Actually we consider generalized Sasakian-space-forms when it is, respectively: \(D\)-concircularly flat; \(D\)-concircular-pseudosymmetric; \(D\)-concircularly Ricci-semisymmetric; \(D\)-concircularly symmetric; \(V(xi,X) .R = 0 ...
