On phi-recurrent generalized Sasakian-space-forms
E. Peyghan, A. Tayebi
We show that there is no phi-recurrent generalized Sasakian-space-forms, when is a non-zero constant.
Two Families of Finsler Metrics Projectively Related to a Kropina Metric
A. Tayebi, H. Sadeghi, E. Peyghan
In this paper, we find the necessary and sufficient conditions under which two classes of (q, a, b)-metrics are projectively related to a Kropina metric.
On phi-Recurrent (k, m)-Contact Metric Manifolds
E. Peyghan, A. Tayebi
In this paper, we show that there is no phi-recurrent Sasakian manifold. Then we prove that the only flat 3-dimensional manifolds are phi-recurrent (k, m)-contact metric manifolds.
On phi-Recurrent Contact Metric Manifolds
E. Peyghan, H. Nasrabadi, A. Tayebi
In this paper, we prove that evry 3-dimensional manifold M is a ?- recurrent N(k)-contact metric manifold if and only if it is flat. Then we classify the ?-recurrent contact metric…
On Cartan Spaces with m-th Root Metrics
A. Tayebi, A. Nankali, E. Peyghan
In this paper, we define some non-Riemannian curvature properties for Cartan spaces. We consider Cartan space with the m-th root metric. We prove that every m-th root Cartan space…
Generalized Isotropic Berwald Manifolds
A. Tayebi, E. Peyghan
In this paper, we construct a new class of Finsler manifolds called generalized isotropic Berwald manifolds which is an extension of the class of isotropic Berwald manifolds. We pr…
