\(\bar\partial\)-regularity for weakly pseudoconvex domains in compact Hermitian symmetric spaces with respect to invariant metrics. (English) Zbl 1030.53071

The following conjecture is proved: Main Theorem. Let \(q\geq 8\). Then there are no \(C^q\) Levi-flat real hypersurface \(M\) in \(\mathbb{P}_2\). (Here the Levi-flatness of \(M\) means that \(M\) is foliated by local complex-analytic curves.).
