In this paper we construct two distinct examples of singularities along the flow. First, we find a finite time singularity, ruling out long time existence of the flow in general. Next we show long time existence of the flow with a Calabi symmetry assumption on the blowup of ℙⁿ, n≥ 3, if one assumes supercritical phase. Using this, we find an example where a singularity occurs at infinite time along the destabilizing subvariety in the semi-stable case.Mean curvature flowLagrangian mean curvature flowSingularitiesKähler geometryLong-time existence & convergence
