[PDF][PDF] On isotropic Berwald metrics

A Tayebi, B Najafi - Ann. Polon. Math, 2012 - researchgate.net
In this paper, we prove that every isotropic Berwald metric of scalar flag curvature is a
Randers metric. We study the relation between an isotropic Berwald metric with a Randers …

We classify all Einstein Randers metric on R 4 constructed from ga, the Hawking Taub–NUT
metric, and a homothetic vector field W for ga in the Zermelo navigation representation. All of …

[PDF][PDF] On generalized Douglas-Weyl spaces

A Tayebi, H Sadeghi, E Peyghan - Bull. Malays. Math. Sci. Soc …, 2013 - kurims.kyoto-u.ac.jp
In this paper, we show that the class of R-quadratic Finsler spaces is a proper subset of the
class of generalized Douglas-Weyl spaces. Then we prove that all generalized Douglas …

On douglas surfaces

In this paper, we consider one of open problems in Finsler geometry which presented by
Chen-Shen on Douglas surfaces. First, we prove that a Finsler surface has isotropie Berwald …

Generalized Berwald metrics

E Peyghan, A Tayebi - Turkish Journal of Mathematics, 2012 - journals.tubitak.gov.tr
In this paper, we consider a class of Finsler metrics called generalized Berwald metrics
which contains the class of Berwald metrics as a special case. We prove that every …

On semi-C-reducibility of (α, β)-metrics

A Tayebi, E Peyghan, B Najafi - International Journal of Geometric …, 2012 - World Scientific
Every non-Riemannian (α, β)-metric on a manifold with dimension n≥ 3 is semi-C-reducible.
Thus the study on semi-C-reducible metrics will enhance our understanding on the physical …

On a subclass of the class of generalized Douglas-Weyl metrics

A Tayebi, E Peyghan - Journal of Contemporary Mathematical Analysis, 2012 - Springer
We study a class of Finsler metrics whose Douglas curvature is constant along any
Finslerian geodesics. This class of Finsler metrics is a subclass of the class of generalized …

[PDF][PDF] Reduce Douglas Metric by Using the Concept of Special Cartan Curvature

S Hedayatian, N Izadian, MY Ahmadi - 2024 - mmr.khu.ac.ir
For a Finsler metric the geodesics curves are characterized by the system of second order
ordinary differential equations. A Finsler metric is called a Berwald metric if the spray …
