On doubly warped product Finsler manifolds

E Peyghan, A Tayebi - Nonlinear Analysis: Real World Applications, 2012 - Elsevier
In this paper, we introduce horizontal and vertical warped product Finsler manifolds. We
prove that every C-reducible or proper Berwaldian doubly warped product Finsler manifold …

Nearly Kahler and nearly Kenmotsu manifolds

N Heidari, NHP KASHANI… - Turkish Journal of …, 2018 - journals.tubitak.gov.tr
We study the class of strict nearly Kenmotsu manifolds and prove that there is no Einstein
manifold or locally symmetric or locally $\phi $-symmetric in this class of manifolds. We …

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 …

[PDF][PDF] On the geometry of tangent bundle of Finsler manifold with Cheeger-Gromoll metric

Z Raei - Journal of Finsler Geometry and its Applications, 2021 - jfga.uma.ac.ir
Let (M, F) be a Finsler manifold and G be the Cheeger-Gromoll metric on TM inducedby F.
We show that the curvature tensor field of the Levi-Civita connection on (TM, G) …

Metric compatible or non-compatible Finsler–Ricci flows

SI Vacaru - International Journal of Geometric Methods in Modern …, 2012 - World Scientific
There were elaborated different models of Finsler geometry using the Cartan (metric
compatible), or Berwald and Chern (metric non-compatible) connections, the Ricci flag …

Some geometrical results on nearly Kähler Finsler manifolds

AD Nezhad, S Beizavi, A Tayebi - Facta Universitatis, Series …, 2022 - casopisi.junis.ni.ac.rs
This work is intended as an attempt to extend some results of nearly Kählerian Finsler
manifolds. We give a condition to generalized $(a, b,{\bf J})-$ manifolds to be weakly …

Horizontal Laplacian on tangent bundle of Finsler manifold with g-natural metric

E Peyghan, A Tayebi, C Zhong - International Journal of Geometric …, 2012 - World Scientific
Recently the third author studied horizontal Laplacians in real Finsler vector bundles and
complex Finsler manifolds. In this paper, we introduce a class of g-natural metrics Ga, b on …

Almost paracontact structures on tangent sphere bundle

E Peyghan, A Naderifard, A Tayebi - International Journal of …, 2013 - World Scientific
Using the almost product structure given by Druta, we introduce a metrical framed f (3,-1)-
structure on the tangent bundle of a Riemannian manifold. Then by restricting this metrical …

[PDF][PDF] Regarding the Kahler-Einstein structure on Cartan spaces with Berwald connection

E Peyghan, A Ahmadi, A Tayebi - 2011 - sid.ir
A Cartan manifold is a smooth manifold M whose slit cotangent bundle T* M0 is endowed
with a regular Hamiltonian K which is positively homogeneous of degree 2 in momenta. The …
