Geodesic mappings and concircular vector fields
Igor G. Shandra
In the present paper we study geodesic mappings of special pseudo-Riemannian manifolds called -spaces. We prove that the set of solutions of the system of equations of geod…

On higher order Codazzi tensors on complete Riemannian manifolds
I. G. Shandra, S. E. Stepanov
We prove several Liouville-type non-existence theorems for higher order Codazzi tensors and classical Codazzi tensors on complete and compact Riemannian manifolds, in particular. T…
