We prove that on these manifolds the quaternionic Monge-Ampère equation is always solvable, extending results of Alesker and of Dinew-Sroka, and we confirm the conjecture on the maximal existence time of the HKT-Ricci flow. On quaternionic Hopf surfaces we construct non-trivial HKT solitons and prove convergence of the normalized flow for symmetric initial data.</description><category>Ricci flow</category><category>Ricci-flat &amp; Calabi–Yau</category><category>Kähler geometry</category><category>Homogeneous spaces</category></item>

This is the same setting in which Dinew and Sroka prove the conjecture of Alesker and Verbitsky. We also introduce an analogue of the Chern-Ricci flow in hyperhermitian manifolds.</description><category>Ricci flow</category><category>Generalized &amp; G₂ flows</category><category>Ricci-flat &amp; Calabi–Yau</category><category>Kähler geometry</category><category>Long-time existence &amp; convergence</category></item>
