本文的主要目的是证明肖岗猜想的曲面纤维基变化的基本不变量的非负性。为此,我们得到了zd=f(x,y)的奇点不变量之间的一些新的不等式。
The main purpose of this paper is to prove the nonnegativity of the basic invariants of base changes of a surface fibration, which is conjectured by Xiao Gang. For this purpose we obtain some new inequalities between the invariants of the singularities ofzd=f(x, y).
