On conformal collineation and almost Ricci solitons
Adara M. Blaga, Bang-Yen Chen
We provide conditions for a Riemannian manifold with a nontrivial closed affine conformal Killing vector field to be isometric to a Euclidean sphere or to the Euclidean space. Also…

Conformal-projective transformations on statistical and semi-Weyl manifolds with torsion
Adara M. Blaga, Antonella Nannicini
We show that statistical and semi-Weyl structures with torsion are invariant under conformal-projective transformations. We prove that a non-degenerate submanifold of a semi-Weyl (…
