چکیده
|
Let f = √α(α + β) be a conformally flat square-root (α; β)-metric on a manifold m of dimension n ≥ 3, where α = √aij(x)yiyj is a riemannian metric and β = bi(x)yi is a 1-form on m. suppose that f has relatively isotropic mean landsberg curvature. we show that f reduces to a riemannianmetric or a locally minkowski metric.
