论文摘要
我们给出了表面组某些元素稳定换向器长度（SCL）合理性的新证明：那些由不填充表面的曲线表示的曲线。这样的元素总是接收SCL的极端表面。这些结果对于非填充1链也更普遍。
We give a new proof of rationality of stable commutator length (scl) of certain elements in surface groups: those represented by curves that do not fill the surface. Such elements always admit extremal surfaces for scl. These results also hold more generally for non-filling 1-chains.
