Einstein warped-product manifolds and the screened Poisson equation
Alexander Pigazzini, Luca Lussardi, Magdalena Toda +1
We study a particular type of Einstein warped-product manifold where the warping function must satisfy the homogeneous version of the screened Poisson equation. Under these assumpt…
