ON f-KENMOTSU MANIFOLDS AND THEIR SUBMANIFOLDS WITH QUARTER SYMMETRIC METRIC CONNECTIONS [PDF]
Facta Universitatis, Series: Mathematics and Informatics, 2021 The object of the present paper is to study invariant submanifolds of f-Kenmotsu manifolds with respect to quarter symmetric metric connections. Some necessary and sufficient conditions for such submanifolds to be totally geodesic have been deduced. Also we construct an example of a submanifold of a five-dimensional f-Kenmotsu manifold to justify our ...

Quarter - symmetric metric connection on a Sasakian manifold
Communications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 2000 A linear metric connection on a Riemannian manifold \(M\) is called quarter-symmetric if its torsion tensor \(T\) satisfies \(T(X,Y) = \pi(Y)F(X) - \pi(X)F(Y)\) with some one-form \(\pi\) and \((1,1)\)-tensor field \(F\) on \(M\). The authors investigate the existence problem of quarter-symmetric metric connections and study curvature properties of ...

Improved Chen’s Inequalities for Submanifolds of Generalized Sasakian-Space-Forms
Axioms, 2022 In this article, we derive Chen’s inequalities involving Chen’s δ-invariant δM, Riemannian invariant δ(m1,⋯,mk), Ricci curvature, Riemannian invariant Θk(2≤k≤m), the scalar curvature and the squared of the mean curvature for submanifolds of generalized ...

On a Quarter-Symmetric Projective Conformal Connection
International Electronic Journal of Geometry, 2017 We introduce a class of quarter-symmetric projective conformal connections, and study thegeometrical properties of a manifold associated with this connection. The Schur’s theoremcorresponding to the quarter-symmetric projective conformal connection is derived.
