论文摘要
我们为欧拉（Euler）特征的带状表面构造了几个无限的三链闭合封闭的家族。我们还使用扭曲的亚历山大多项式障碍物来结论平滑的切片结的分类，这是交替的3架交替的，最多20个交叉点的封闭。
We construct ribbon surfaces of Euler characteristic one for several infinite families of alternating 3-braid closures. We also use a twisted Alexander polynomial obstruction to conclude the classification of smoothly slice knots which are closures of alternating 3-braids with up to 20 crossings.
