令 V 为在 C 上定义的法线曲面。根据[3],如果 V 的所有奇点都是商类型,我们称 V 是对数的。如果它的有理系数的约简同调群全部消失,则称为 Q 同调平面。令 J^ = {pi,...,pr} 表示 V 的奇点集。然后回想一下,V 的对数 Kodaira 维数定义为 V \ ^ 的对数 Kodaira 维数。在以此开头的一系列三篇文章中,我们建议探讨以下问题:
Let V be a normal surface defined over C. Following [3], we say V is logarithmic if all its singularities are of quotient type. It is called a Q-homology plane if its reduced homology groups with rational coefficients all vanish. Let J^ = {pi, ,pr} denote the set of singularities of V. Then recall that the logarithmic Kodaira dimension of V is defined to be the logarithmic Kodaira dimension of V \ ^ . In a sequence of three articles beginning with this, we propose to probe the following questions:
