A Concurrent Generalized Kropina Change
A. Soleiman, Ebtsam H. Taha
This paper investigates a generalized Kropina metric featuring a specific -form. Start with a Finsler manifold admits a concurrent -vector field , then, e…
Special anisotropic conformal changes of conic pseudo-Finsler surfaces
Nabil L. Youssef, Ebtsam H. Taha, A. A. Kotb +1
This study presents many special anisotropic conformal changes of a conic pseudo-Finsler surface , such as -anisotropic and horizontal -anisotropic conformal transform…
Anisotropic conformal change of conic pseudo-Finsler surfaces, II
Nabil L. Youssef, S. G. Elgendi, A. A. Kotb +1
This paper is a continuation of our investigation of the anisotropic conformal change of a conic pseudo-Finsler surface , namely, the change $\overline{F}(x,y)=e^{ϕ(x,y)}F(x…
Semi Concurrent vector fields in Finsler geometry
Nabil L. Youssef, S. G. Elgendi, Ebtsam H. Taha
In the present paper, we introduce and investigate the notion of a semi concurrent vector field on a Finsler manifold. We show that some special Finsler manifolds admitting such ve…
