ON RICCI SOLITONS AND SUBMANIFOLDS WITH A SEMI-SYMMETRIC NON-METRIC CONNECTION [PDF]

Facta Universitatis Series Mathematics and Informatics
We consider Ricci solitons with a semi-symmetric non-metric connection. We find some properties, when the potential vector field is torse-forming. Applications to submanifolds are also given.

On concircular and torse-forming vector fields on compact manifolds

, 2010
Summary: In this paper we modify the theorem by E. Hopf and found results and conditions, on which concircular, convergent and torse-forming vector fields exist on (pseudo-) Riemannian spaces. These results are applied for conformal, geodesic and holomorphically projective mappings of special compact spaces without boundary.

Certain results on \(N(k)\)-contact metric manifolds and torse-forming vector fields

2021
A contact metric manifold \(M\) is called \(N(k)\)-contact metric manifold if \(M\) is endowed with a \(k\)-nullity distribution. The author studies the properties of these manifolds endowed with a torse-forming vector field and admitting a Ricci soliton. Let us mention some of these results.

Geometric structure of Galilean spacetimes admitting a conformally Leibnizian vector field

Physica Scripta
In this paper we study the geometric structure of Galilean spacetimes that possess a certain type of infinitesimal symmetries. Specifically, we assume the existence of vector fields whose flow generates conformal transformations of the Leibnizian ...
