Flow by mean curvature inside a moving ambient space
Annibale Magni, Carlo Mantegazza, Efstratios Tsatis
We show some computations related to the motion by mean curvature flow of a submanifold inside an ambient Riemannian manifold evolving by Ricci or backward Ricci flow. Special emph…
Ancient solutions of Ricci flow on spheres and generalized Hopf fibrations
Ioannis Bakas, Shengli Kong, Lei Ni
Ancient solutions arise in the study of Ricci flow singularities. Motivated by the work of Fateev on 3-dimensional ancient solutions we construct high dimensional ancient solutions…
Invariant Einstein metrics on flag manifolds with four isotropy summands
Andreas Arvanitoyeorgos, Ioannis Chrysikos
A generalized flag manifold is a homogeneous space of the form , where is the centralizer of a torus in a compact connected semisimple Lie group . We classify all flag…
Invariant Einstein metrics on generalized flag manifolds with two isotropy summands
Andreas Arvanitoyeorgos, Ioannis Chrysikos
Let be a generalized flag manifold, that is the adjoint orbit of a compact semisimple Lie group . We use the variational approach to find invariant Einstein metrics for…
