DDVV Inequality on Submanifolds Coupled with a Slant Factor in Quaternionic Kaehler Manifolds

Axioms
This work aims to provide generalized Wintgen inequalities for slant submanifolds embedded in quaternionic space forms, taking into consideration both semi-symmetric metric and semi-symmetric non-metric connections.

THE IMPACT OF SEMI-SYMMETRIC NON-METRIC CONNECTION ON A 3-DIMENSIONAL RIEMANNIAN MANIFOLD ADMITTING SOLITONS [PDF]

This article carries out the investigation of a 3-dimensional Riemannian manifold M^3 endowed with a semi-symmetric type of non-metric connection. After introduction, we provide the basic results of semi-symmetric non-metric connection.

Bi-paracontact structures and Legendre foliations [PDF]

, 2002
We study almost bi-paracontact structures on contact manifolds. We prove that if an almost bi-paracontact structure is defined on a contact manifold $(M,\eta)$, then under some natural assumptions of integrability, $M$ carries two transverse bi ...

On A Semi-Symmetric Non Metric Connection in Lorentzian Para-Cosympletic Manifold

Journal of the Tensor Society, 2009
In this paper we define and studied a semi-symmetric non metric connection on a Lorentzian Para-Cosympletic Manifold and prove its existence. We deduce the expression for curvature tensor and Ricci tensor of semi-symmetric non metric connection defined.

Generlized Quasi-Sasakian Manifold admitting Semi-Symmetric Non Metric Connection

Journal of the Tensor Society, 2008
Agashe and Chafle [4] defined a semi – symmetric non-etric connection in a Riemannian manifold. Further, the properties of semi- symmetric non-metric connection in almost contact metric manifold has been studied by Ojha and Prasad [5]. The purpose of this paper is to introduce a semi-symmetric non-metric connection in generalized quasi-sasakian ...

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

Advanced 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.

A spectral curve approach to Lawson symmetric CMC surfaces of genus 2

, 2013
Minimal and CMC surfaces in $S^3$ can be treated via their associated family of flat $\SL(2,\C)$-connections. In this the paper we parametrize the moduli space of flat $\SL(2,\C)$-connections on the Lawson minimal surface of genus 2 which are equivariant
