Let $(M,\mathsf{G})$ be a cohomogeneity one manifold, let $\mathcal{B}$ be a stably Ricci-diagonal basis for it, and let $\mathrm{g}_0$ be a metric on $M$ that is diagonal with res…

A compact nearly Kähler manifold is cohomogeneity one if it is equipped with an isometric action of a compact Lie group whose generic orbits have codimension one. Foscolo–Haskins c…
