Hacon–Kovács–Luo–Zhang conjecture on zeros of holomorphic one-forms

About 14 years old · traced to

Let XX be a smooth complex projective variety of general type. For a global holomorphic one-form ω∈H0(X,ΩX1)\omega\in H^0(X,\Omega_X^1), define its zero locus by

Z(ω)={x∈X∣ω(TxX)=0}.Z(\omega)=\{x\in X\mid \omega(T_xX)=0\}.

Hacon–Kovács–Luo–Zhang conjecture. The zero locus Z(ω)Z(\omega) is nonempty for every global holomorphic one-form ω∈H0(X,ΩX1)\omega\in H^0(X,\Omega_X^1).

The conjecture concerns the existence of zeros of holomorphic one-forms on varieties of general type. It is tautological for curves, and was known for surfaces, threefolds, varieties with ample canonical bundle, and more generally minimal varieties; the supplied text does not establish that the conjecture is solved in full generality.
