Campana's cotangent-dimension equality conjecture

About 4 years old · traced to

Let XX be a compact connected Kähler manifold and let p>0p>0. Write

νp(X):=ν(X,ΩXp),κp(X):=κ(X,ΩXp).\nu_p(X):=\nu(X,\Omega_X^p),\qquad \kappa_p(X):=\kappa(X,\Omega_X^p).

The cotangent-dimension equality conjecture. One has

νp(X)=κp(X).\nu_p(X)=\kappa_p(X).

This extends the canonical-bundle equality to all exterior powers of the cotangent bundle; the paper does not establish it in general.
