On Conformally Flat ۵-th root (α, β)-Metrics with Relatively Isotropic Mean Landsberg Curvature

In this paper, we study conformally flat ۵-th root (α, β)-metrics. We prove that everyconformally flat ۵-th root (α, β)-metric with relatively isotropic mean Landsberg curvaturemust be either Riemannian metrics or locally Minkowski metrics.
