论文摘要
我们表明，如果复合$θ$ -Curve具有（适当的理性）脱节第一，那么它是A（适当理性的）Untnekting第一结和琐碎的$θ$ curve的订单2总和。我们还证明了2链缠结和结节的结果相似。
We show that if a composite $θ$-curve has (proper rational) unknotting number one, then it is the order 2 sum of a (proper rational) unknotting number one knot and a trivial $θ$-curve. We also prove similar results for 2-strand tangles and knotoids.
