Esnault's finite-fundamental-group conjecture for Kähler manifolds

About 2 years old · traced to

Let XX be a compact Kähler manifold. Let ΩX1\Omega_X^1 denote its cotangent bundle, and let H0(X,Sym⁡mΩX1)H^0(X,\operatorname{Sym}^m\Omega_X^1) be the space of holomorphic symmetric mm-differentials.

Esnault's conjecture. If

H0(X,Sym⁡mΩX1)=0H^0(X,\operatorname{Sym}^m\Omega_X^1)=0

for all m>0m>0, then the fundamental group of XX is finite.

The parser marks this conjecture as resolved. The source notes that a slightly weaker statement was known: under the same vanishing condition, the fundamental group has no linear representation with infinite image.
