Abstract

Let FF be a homogeneous (α1,α2)(\alpha_1,\alpha_2) metric on the reductive homogeneous manifold G/HG/H. Firstly, we characterize the natural reductiveness of FF as a local ff-product between naturally reductive Riemannian metrics. Secondly, we prove the equivalence among several properties of FF for its mean Berwald curvature and S-curvature. Finally, we find an explicit flag curvature formula when FF is naturally reductive.
