关于$H^2$和有理簇的Beilinson-Hodge猜想

On the Beilinson-Hodge conjecture for $H^2$ and rational varieties

Andre Chatzistamatiou

摘要:

Beilinson-Hodge猜想证明了循环映射$$H^n_M(X,\Q(n)) \to {\rm Hom}_{MHS}(\Q(-n),H^n(X,\Q))$$对所有正整数$n$和所有光滑复代数簇$X$的满射性。对于$n=2$,如果$X$是有理数,则证明了猜想.

英文摘要:

The Beilinson-Hodge conjecture asserts the surjectivity of the cycle map $$H^n_M(X,\Q(n)) \to {\rm Hom}_{MHS}(\Q(-n),H^n(X,\Q))$$ for all positive integers $n$ and every smooth complex algebraic variety $X$. For $n=2$, we prove the conjecture if $X$ is rational.
