Inoue-surface Chern-Ricci flow convergence conjecture

From papers

Let MM be any Inoue surface. Let ω(t)\omega(t) be the Chern-Ricci flow and let ω\omega_\infty be the closed semipositive (1,1)(1,1)-form representing a multiple of c1(KM)c_1(K_M) described in the source. Inoue-surface convergence conjecture. For any Hermitian initial metric ω0\omega_0, without requiring it to be Gauduchon or making an initial conformal change, the convergence

ω(t)tω\frac{\omega(t)}{t}\to\omega_\infty

is uniform; it is in fact CC^\infty, and there is a constant CC such that

Rm(ω(t)t)g(t)/tC\left|\operatorname{Rm}\left(\frac{\omega(t)}{t}\right)\right|_{g(t)/t}\leqslant C

on MM for all sufficiently large tt. Existing results establish these conclusions for restricted classes of initial metrics, while the fully arbitrary-Hermitian statement remains open.
