Collineation varieties of tensors

Collectanea Mathematica, 2023
In this article, we introduce the k-th collineation variety of a third order tensor. This is the closure of the image of the rational map of size k minors of a matrix of linear forms associated to the tensor.

Journal of Geometry and Physics, 2022
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.
