| چکیده | ||
| This paper is devoted to the study of generalized Randers change in a specific class of (α,β)-metrics of conformally flat type. These metrics are defined as F = αexp(β/α) + εβ, where ε ̸= 0 is a real constant, and are called the generalized Randers change(G.R.C.) of the exponential metric. We demonstrate that if F possesses a relatively isotropic mean Landsberg curvature, it must either be a Riemannian or a locally Minkowskian metric. Furthermore, if F is a non-Riemannian weak Einstein metric, it necessarily reduces to a locally Minkowskian metric. | ||
