Einstein doubly warped product manifolds with semi-symmetric metric connection

open access: yesActa Mathematica, 2020
In this paper, we study the doubly warped product manifolds with semi-symmetric metric connection. We derive the curvature formulas for doubly warped product manifold with semi-symmetric metric connection in terms of curvatures of components of doubly warped product manifolds.

Geometries for a mutual connection of semi-symmetric metric recurrent connections

open access: yesFilomat, 2020
A semi-symmetric metric recurrent connection has already been studied. In this paper we newly discovered geometrical properties and conjugate symmetric condition for the mutual connection of a semi-symmetric metric recurrent connection in a Riemannian manifold.

Almost Complex and Hypercomplex Norden Structures Induced by Natural Riemann Extensions

open access: yesMathematics, 2022
The Riemann extension, introduced by E. K. Patterson and A. G. Walker, is a semi-Riemannian metric with a neutral signature on the cotangent bundle T∗M of a smooth manifold M, induced by a symmetric linear connection ∇ on M.

On a semi symmetric metric connection with a special condition on a Riemannian manifold [PDF]

open access: yes, 2011
In this study, we consider a manifold equipped with semi symmetric metric connection whose the torsion tensor satisfies a special condition. We investigate some properties of the Ricci tensor and the curvature tensor of this manifold .

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

open access: yesAdvanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Semi-symmetric Metric Connections, Einstein Manifolds and Projective Curvature Tensor [PDF]

open access: yes, 2010
Riemananian Manifolds admitting a semi-symmetric metric connection are an important class of manifolds. Such connections give rise to interesting generalizations of Einstein manifolds and projective curvature tensor.We also demonstrate the close ...
