Curvature constrained on base for $(2+m)$-Einstein warped product manifolds

Alexander Pigazzini, Cenap Ozel, Saeid Jafari

For the studied cases in [10], the author showed that having the {\textit {$f$-curvature-Base}} ($R_{f_B}$) is equal to requiring a flat metric on the base-manifold. In [11] the au…
