论文摘要
我们为紧凑型Riemann表面之间的圆形图的纤维产品组件的属提供了下限，从而扩展了表格$ a（x）-b（y）= 0的代数曲线组件的属结果，其中$ a $ a $ a $ a $和$ b $是合理的功能。
We give lower bounds for genera of components of fiber products of holomorphic maps between compact Riemann surfaces, extending results on genera of components of algebraic curves of the form $A(x)-B(y)=0,$ where $A$ and $B$ are rational functions.
