Homogeneous spaces with two equivalent isotropy summands develop positive Ricci curvature under Ricci flow
Eric Cochran, Arseny Mingajev, Lawrence Mouillé +2
We study normalized Ricci flow on simply connected homogeneous spaces G/H for which the isotropy representation splits into exactly two equivalent irreducible subrepresentations. W…

On Nilpotent and Solvable Quasi-Einstein Manifolds
Nazia Valiyakath
In this paper, we investigate nilpotent and unimodular solvable Lie groups that admit quasi-Einstein metrics with a left-invariant vector field, which we call \emph{t…
