A note on L. Zhou's result on Finsler surfaces with and
S. G. Elgendi, Nabil L. Youssef
In this note, we show that the examples of non Berwaldian Landsberg surfaces with vanishing flag curvature, obtained in \cite{Zhou}, are in fact Berwaldian. Consequently, Bryant's…
Solutions for the Landsberg unicorn problem in Finsler geometry
S. G. Elgendi
It is still a long-standing open problem in Finsler geometry, is there any regular Landsberg metric which is not Berwaldian. However, there are non-regular Landsberg metrics which…
Coordinate-free study of Finsler spaces of -scalar curvature
A. Soleiman, S. G. Elgendi
The aim of the present paper is to provide an \emph{intrinsic} investigation of special Finsler spaces of -scalar curvature and of -constant curvature. Characteriza…
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…
