If the Mabuchi functional is proper modulo automorphisms, the flow converges exponentially to a constant scalar curvature Kähler (cscK) metric. In particular, this gives a flow proof that properness of the K-energy implies the existence of a cscK metric in the toric setting.</description><category>Other curvature flows</category><category>Kähler geometry</category><category>Scalar curvature</category><category>Long-time existence &amp; convergence</category><category>Kähler–Einstein &amp; K-stability</category></item>

As an application, we show that if the initial data has volume form C⁰ close to that of a cscK metric, then the pseudo Calabi flow exists for t∈ (0,+∞). We also prove similar improvement of regularity and long time existence result for pseudo Calabi flow on a Fano manifold when the volume form is bounded and the class is close to c₁(M).</description><category>Other curvature flows</category><category>Kähler geometry</category><category>Long-time existence &amp; convergence</category><category>Kähler–Einstein &amp; K-stability</category></item>
