In this paper, it is shown that for a 3-dimensional compact simply connected trans-Sasakian manifold of type (α, β), the smooth functions α, β satisfy the Poisson equations Δα = β, Δα = α2β and Δβ = α2β, respectively, if and only if it is homothetic to a Sasakian manifold. We also find a necessary and sufficient condition for a connected 3-dimensional trans-Sasakian manifold of type (α, β) in terms of a differential equation satisfied by the smooth function α to be homothetic to a Sasakian manifold
We aim to examine the influence of the existence of a nonzero eigenvector z of the de-Rham
operator G on a k-dimensional Riemannian manifold (Nk, g). If the vector z annihilates the de-Rham…
The Fischer-Marsden conjecture asserts that an n-dimensional compact manifold admitting a nontrivial solution of the so-called Fischer-Marsden differential equation is necessarily an Einstein…
We use a nontrivial concircular vector field u on the unit sphere Sn+1 in studying
geometry of its hypersurfaces. An orientable hypersurface M of the unit sphere Sn+1
naturally…
