Letters in Mathematical Physics, 1999
The authors write an ansatz for quasi-Einstein Kähler metrics (also called Kähler Ricci solitons) and construct new examples on complex line bundles (or their compactifications \({\mathbf P}(\mathcal{O}\otimes L)\)) over Kähler-Einstein base manifolds \(B\). Firstly, the authors obtain in Sect. 2 an ansatz for quasi-Einstein Kähler metrics with a torus

Six-dimensional Lie–Einstein metrics
Journal of Geometry, 2021On an Einstein manifold the Ricci tensor is a multiple of the metric. In the present paper the authors study Einstein manifolds that arise for right-invariant Riemannian metrics on a six-dimensional Lie group \(G\). They impose severe restrictions on the Lie algebra it-self: indecomposable, six-dimensional and solvable.

Motivated by Koiso’s work on quasi-Einstein metrics on Fano manifolds, we define (generalized) quasi-Einstein metrics in any Kähler class on any compact complex manifold. It turns out that these metrics are similar to Calabi’s Extremal metrics. Moreover their existence might be studied by a curvature flow in a given Kähler class.

Let \((M,F)\) be a Finsler manifold and \(\mathbb R\), in Z. Shen's terminology, its Riemann curvature. (Other terms: affine deviation tensor - L. Berwald; Jacobi endomorphism - W. Sarlet and his collaborators.) The function \(\sigma:=\frac{1}{F^2}\text{tr}\mathbb{R}\) is the Ricci-scalar of \((M,F)\).
