Leafwise flat forms on Inoue-Bombieri surfaces

We prove that every Gauduchon metric on an Inoue-Bombieri surface admits a strongly leafwise flat form in its $\mathrm{\partial }\bar{\mathrm{\partial }}$-class. Using this result, we deduce uniform convergence of the normalized Chern-Ricci flow starting at any Gauduchon metric on all Inoue-Bombieri surfaces. We also show that the convergence is smooth with bounded curvature for initial metrics in the $\mathrm{\partial }\bar{\mathrm{\partial }}$-class of the Tricerri/Vaisman metric.
