Canonical surgeries in rotationally invariant Ricci flow
Timothy Buttsworth, Maximilien Hallgren, Yongjia Zhang
We construct a rotationally invariant Ricci flow through surgery starting at any closed rotationally invariant Riemannian manifold. We demonstrate that a sequence of such Ricci flo…
-invariant Ricci solitons and ancient flows on
Timothy Buttsworth
Consider the standard action of on . We establish the existence of a uniform constant so that any…
Prescribing Ricci curvature on a Product of Spheres
Timothy Buttsworth, Anusha M. Krishnan
We prove an existence result for the prescribed Ricci curvature equation for certain doubly warped product metrics on , where $d_i \geq 2…
Deducing Flux from Single Point Temperature History when Relative Spatial Variation of Flux is Prescribed
David Buttsworth, Timothy Buttsworth
Surface heat transfer in convective and radiative environments is sometimes measured by recording the surface temperature history in a transient experiment and interpreting this su…
Local Stability of Einstein Metrics Under the Ricci Iteration
Timothy Buttsworth, Maximilien Hallgren
We provide a sufficient condition for the local stability of closed Einstein manifolds of positive Ricci curvature under the Ricci iteration in terms of the spectrum of the Lichner…
Cohomogeneity-One Quasi-Einstein Metrics
Timothy Buttsworth
Let be a connected, simply connected homogeneous space of a compact Lie group . We study -invariant quasi-Einstein metrics on the cohomogeneity one manifold $G/H\times…
