Abstract: I will discuss local Calabi estimates for solutions to the continuity equation on Hermitian manifolds, introduced by La Nave-Tian and extended to Hermitian metrics by Sherman-Weinkove. We apply the estimates to show that on a compact complex manifold the Chern scalar curvature of a solution must blow up at a finite-time singularity. Additionally, starting from certain classes of initial data on Oeljeklaus-Toma manifolds we prove Gromov-Hausdorff and smooth convergence of the metric to a particular non-negative $(1,1)$-form. This is joint work with Xi Sisi Shen and Kevin Smith.
