节曲线间分界线

Divisibilities among nodal curves

Matthias Schuett

摘要:

利用可除性证明了光滑代数曲面上的节曲线不存在有效或反有效的平方-1或平方-2类。这个一般的事实有有趣的应用恩里克斯和K3曲面。该证明依赖于根格的特定性质及其性质。

英文摘要:

We prove that there are no effective or anti-effective classes of square -1 or -2 arising from nodal curves on smooth algebraic surfaces by way of divisibility. This general fact has interesting applications to Enriques and K3 surfaces. The proof relies on specific properties of root lattices and their duals.
