Ricci solitons on contact pseudo-metric manifolds
Eftekhar Asgharzadeh, Morteza Faghfouri
In this paper, we prove that a Sasakian pseudo-metric manifold which admits an Ricci soliton is an Einstein manifold, and if the potential vector field of the Ricci sol…
On contact pseudo-metric manifolds satisfying a nullity condition
Narges Ghaffarzadeh, Morteza Faghfouri
In this paper, we aim to introduce and study -contact pseudo-metric manifold and prove that if the -sectional curvature of any point of is independent of the choice…

Narges Ghaffarzadeh, Morteza Faghfouri
In this paper, we introduce a contact pseudo-metric structure on a tangent sphere bundle . we prove that the tangent sphere bundle is -c…
On anti-invariant semi-Riemannian submersions from Lorentzian (para)Sasakian manifolds
Morteza Faghfouri, Sahar Mashmouli
In this paper we study a semi-Riemannian submersion from Lorentzian (para)almost contact manifolds and find necessary and sufficient conditions for the characteristic vector field…

We study Einstein's equation in and warped spaces and classify all such spaces satisfying Einstein equations . We show…
Chen's inequality for C-totally real submanifolds in a generalized -space form
Morteza Faghfouri, Narges Ghaffarzadeh
In this paper, we obtain a basic Chen's inequality for a C-totally real submanifold in a generalized -contact space forms involving intrinsic invariants, namely the scalar c…
A note on 2-dimensional Finsler manifold
Morteza Faghfouri, Rahim Hosseinoghli
We solve the following problem for Is any n-dimensional Finsler manifold with a function which is nonconstant and smooth on satisfying $ \dfrac{\partial g^{…
On doubly warped product submanifolds of Generalized -Space Forms
Morteza Faghfouri, Narges Ghaffarzadeh

On doubly warped product immersions
Morteza Faghfouri, Ayyoub Majidi
In this paper we study fundamental geometric properties of doubly warped product immersion which is an extension of warped product immersion. Moreover, we study geometric inequalit…
On the push-out space
Morteza Fathy, Morteza Faghfouri
Let be an immersion where is a smooth connected -dimensional manifold without boundary. Then we construct a subspace of $ \mathbb{…
