Kato's homological conjecture for smooth projective varieties

About 17 years old · traced to

Let XX be a connected projective smooth variety over kk, and let HiK(X,n):=Hi1,0(X,n)H_i^K(X,n):=H_i^{1,0}(X,n) denote its Kato homology with coefficients in Z/n\mathbb{Z}/n. Then

HiK(X,n)≃{0if i≠0,Z/nif i=0.H_i^K(X,n)\simeq \begin{cases} 0 & \text{if } i\ne 0,\\ \mathbb{Z}/n & \text{if } i=0. \end{cases}

Kato's conjecture. The displayed isomorphism holds. This is a cohomological Hasse-principle prediction for Kato homology of smooth projective varieties over the field kk; the supplied source does not state which cases are known or whether the conjecture has been resolved.
