On some special symmetries of a biwarped product-type 3-manifold
Adara M. Blaga
We investigate special Killing vector fields on 3-dimensional Riemannian manifolds of biwarped product-type. Starting from a diagonal metric on determined by two nont…
On certain symmetries of with a diagonal metric
Adara M. Blaga
We determine Killing vector fields on the -dimensional space endowed with a special diagonal metric.
Flat 3-manifolds with diagonal metrics and applications to warped products
Adara M. Blaga, Dan Radu Latcu
We provide necessary and sufficient conditions for a -dimensional submanifold of endowed with a diagonal metric to be flat. As applications, we characterize the fl…
Constructing Ricci vector fields on with a diagonal metric
Adara M. Blaga
We put into light Ricci vector fields on endowed with a diagonal metric.
On generalized plastic structures
Adara M. Blaga, Antonella Nannicini
We introduce the concept of generalized almost plastic structure, and, on a pseudo-Riemannian manifold endowed with two -tensor fields satisfying some compatibility conditio…
Certain symmetries of with diagonal metrics
Adara M. Blaga
We put into light the Killing vector fields on endowed with a family of diagonal Riemannian metrics. According to certain restrictions on the Lamé coefficients, we co…
