Self-$K$-isocorrespondence conjecture. If there exists a self-$K$-isocorrespondence $\Sigma\subset X\times X$ passing through an arbitrary pair $(x,y)$, then

Let $X$ be a strict Calabi–Yau manifold of dimension $n$, and let $\omega_X\in H^0(X,K_X)$ be a nowhere-zero top-degree holomorphic form. Let $Z\in CH^n(X\times X)_{\mathbb Q}$ be…

Let $X$ and $Y$ be smooth projective varieties of dimension $n$, and let $Z\in CH^n(X\times Y)_{\mathbb Q}$ be a correspondence. Let $F^\bullet$ be the Bloch–Beilinson filtration a…
