In this note, we determine all the homogeneous structures on non-symmetric three-dimensional Riemannian Lie groups. We show that a non-symmetric three-dimensional Riemannian Lie group admits a non-canonical homogeneous structure if and only if its is

We show that four-dimensional homogeneous Kähler Ricci solitons are Einstein, rigid or an algebraic Ricci soliton on the only 3 3 -symmetric space.

Homogeneous conformally Einstein manifolds are classified in dimension four. As a consequence we show that any homogeneous strictly Bach-flat four-dimensional manifold is homothetic to one of the examples constructed by Abbena, Garbiero and Salamon i

We examine the harmonicity of some natural maps associated to the tangent and cotangent bundles, providing some new examples of proper biharmonic maps between pseudo-Riemannian manifolds.

Motivated by the construction of Bach flat neutral signature Riemannian extensions, we study the space of parallel trace-free tensors of type (1, 1) on an affine surface. It is shown that the existence of such a parallel tensor field is characterized
