In this paper, we study generalized Douglas–Weyl (α, β)-metrics. Suppose that a regular (α,
β)-metric F is not of Randers type. We prove that F is a generalized Douglas–Weyl metric …

By an interesting physical perspective and a suitable contraction of the Riemannian
curvature tensor in Finsler geometry, Akbar-Zadeh introduced the notion of scalar curvature …

In this paper, we define a weaker notion of Douglas metrics, namely weakly Douglas
metrics. A Finsler metric satisfies a projectively invariant equation D^ i_\,\, jkl= T_ jkl y^ i D …

Finsler metrics of quadratic curvatures form a rich and important class of metrics. In this
paper, we study spherically symmetric metrics of quadratic curvatures. We find equations …

This paper introduces a new quantity in Finsler geometry, called the generalized Berwald
projective Weyl (GBW~) metric. The C-projective invariance of these metrics is …

In this paper, we study D-recurrent Finsler metrics and characterize D-recurrent Randers
metrics. Indeed, we show that a Randers metric F= α+ β F= α+ β is D-recurrent if and only if d …

Recent studies show that warped product manifolds are useful in differential geometry as
well as in physics. The goal of this paper is to study on some projective invariants of a …

Abstract We characterize generalized Douglas-Weyl Randers metrics in terms of their
Zermelo navigation data. Then, we study the Randers metrics induced by some important …
