Abstract
Let M be a smooth manifold with Finsler metric F, and let \(\widetilde{TM}\) be the slit tangent bundle of M with a generalized Riemannian metric G, which is induced by F. In this paper, we prove that (i) (M, F) is a Landsberg manifold if and only if the vertical foliation F V is totally geodesic in (\(\widetilde{TM}\),G); (ii) letting a:= a(τ) be a positive function of τ = F 2 and k, c be two positive numbers such that \(c = \sqrt {\tfrac{2} {{k(1 + a)}}} \) , then (M,F) is of constant curvature k if and only if the restriction of G on the c-indicatrix bundle IM(c) is bundle-like for the horizontal Liouville foliation on IM(c), if and only if the horizontal Liouville vector field is a Killing vector field on (IM(c),G), if and only if the curvature-angular form Λ of (M,F) satisfies \(\Lambda = \tfrac{{1 - a}} {2}R \) on IM(c).
