论文摘要
我们构建了一个古老的解决方案，以缩短平面曲线。该解决方案始终是紧凑的，并嵌入。对于$ t \ ll0 $，它是由旋转的阳soliton近似的，以有限的角度$α（t）= -t $截断，并被Grim Reaper Transling soliton的小副本封闭。
We construct an ancient solution to planar curve shortening. The solution is at all times compact and embedded. For $t\ll0$ it is approximated by the rotating Yin-Yang soliton, truncated at a finite angle $α(t) = -t$, and closed off by a small copy of the Grim Reaper translating soliton.
