[HTML][HTML] On conformally flat fourth root (α, β)-metrics

A Tayebi, M Razgordani - Differential Geometry and its Applications, 2019 - Elsevier
The theory of 4-th root metrics plays an important role in Biology, General Relativity and
Seismic Ray Theory. Using the Shen's sy-separating trick, we prove that every conformally …

[HTML][HTML] A new class of projectively flat Finsler metrics with constant flag curvature K= 1

In this paper, we consider a class of Finsler metrics which obtained by Kropina change of the
class of generalized m-th root Finsler metrics. We classify projectively flat Finsler metrics in …

A Tayebi - Mathematica Slovaca, 2018 - degruyter.com
By an interesting physical perspective and a suitable contraction of the Riemannian
curvature tensor in Finsler geometry, Akbar-Zadeh introduced the notion of scalar curvature …

In this paper, we characterize locally dually flat generalized m-th root Finsler metrics. Then
we find a condition under which a generalized m-th root metric is projectively related to a m …

On 4-th root metrics of isotropic scalar curvature

A Tayebi - Mathematica Slovaca, 2020 - degruyter.com
In this paper, we prove that every non-Riemannian 4-th root metric of isotropic scalar
curvature has vanishing scalar curvature. Then, we show that every 4-th root metric of …

On Kropina change of m-th root Finsler metrics

necessary and sufficient condition under which the Kropina change of an $ m $-th root …

Some curvature properties of Cartan spaces with mth root metrics

A Tayebi, A Nankali, E Peyghan - Lithuanian Mathematical Journal, 2014 - Springer
In this paper, we define some non-Riemannian curvature properties for Cartan spaces. We
consider a Cartan space with the m th root metric. We prove that every m th root Cartan …
