The existence and uniqueness of Hashiguchi connection in KG-approach

S. G. Elgendi, A. Soleiman

In this study, we treat intrinsic Finsler geometry using the Klein-Grifone approach (KG-approach). A uniqueness and existence theorem for the Hashiguchi connection on a Finsler man…

Vacuum Homogeneous and Nonhomogeneous Metrics with Conventional and Quantized Metric Tensor: Singular or Nonsingular Solution

A. Tawfik, S. G. Elgendi, M. Hanafy

To investigate whether the Universe underwent a singularity or maintained a nonsingular state, we carry out analytical and numerical analyses of the evolution of the Raychaudhuri e…

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(…

On the covariant coefficients of geodesic sprays on Finsler manifolds

S. G. Elgendi, A. Soleiman, Nabil L. Youssef

For a Finsler metric , we introduce the notion of -covariant coefficients of the geodesic spray of (Def. 3.1). We study some geometric consequences concerning the o…

Parallel one forms on special Finsler manifolds

Salah G. Elgendi

In this paper, we investigate the existence of parallel 1-forms on specific Finsler manifolds. We demonstrate that Landsberg manifolds admitting a parallel 1-form have a mean Berwa…
