4 results for Einstein-Kropina

In this article, we study Einstein Kropina metrics on Lie groups and homogeneous spaces. We give a method to construct Einstein Kropina metrics on Lie groups. As an example of this method, a family of non-Riemannian Einstein Kropina metrics on the special orthogonal group SO(n)SO(n) is given. Then, we classify all left in…

Einstein-Kropina metrics extend Einstein condition to all signatures and classify Finsler gravity solutions.

problem Einstein-Kropina metrics in Finsler gravity
method Generalize Einstein condition and classify solutions
result All Einstein-Kropina solutions to the ΛΛ-vacuum equation are Berwald and Ricci-flat, with vanishing cosmological constant.

In this paper, a characteristic condition of Einstein Kropina metrics is given. By the characteristic condition, we prove that a non-Riemannian Kropina metric F=α2βF=\frac{α^2}β with constant Killing form ββ on an n-dimensional manifold MM, n2n\geq 2, is an Einstein metric if and only if αα is also an Einstein metric. …
