一类K3曲面的自积的Hodge猜想

The Hodge conjecture for self-products of certain K3 surfaces

Ulrich Schlickewei

摘要:

本文利用van Geemen的一个结果,确定了K3曲面的Kuga-Satake簇的实乘法自同态代数。应用这一方法证明了$\PP^2$的双覆盖的自积的Hodge猜想,该双覆盖是沿六条线分歧的.

英文摘要:

We use a result of van Geemen to determine the endomorphism algebra of the Kuga--Satake variety of a K3 surface with real multiplication. This is applied to prove the Hodge conjecture for self-products of double covers of $\PP^2$ which are ramified along six lines.
