具有正特征的Bogomolov-Miyaoka-Yau曲面

Surfaces Violating Bogomolov-Miyaoka-Yau in Positive Characteristic

Robert Easton

摘要:

Bogomolov-Miyaoka-Yau不等式断言特征为0的一般类型曲面X的Chern数满足不等式c_1^2 <= 3c_2,其结果是(K_X^2)/chi(O_X)<= 9。这个不等式失败的特征p,在这里,我们产生无限的家庭的反例大p。我们的方法平行建设Hirzebruch,并依赖于建设的阿贝尔覆盖由于Catanese和Pardini。

英文摘要:

The Bogomolov-Miyaoka-Yau inequality asserts that the Chern numbers of a surface X of general type in characteristic 0 satisfy the inequality c_1^2 <= 3c_2, a consequence of which is (K_X^2)/chi(O_X) <= 9. This inequality fails in characteristic p, and here we produce infinite families of counterexamples for large p. Our method parallels a construction of Hirzebruch, and relies on a construction of abelian covers due to Catanese and Pardini.
