报告摘要
In the previous talk, we introduced sign stability for mutation loops as a generalization of pseudo-Anosov mapping classes. In this talk, we show that pseudo-Anosov mapping classes are, in fact, sign-stable as mutation loops. Furthermore, we demonstrate that "generic" pseudo-Anosovness can be characterized by "uniform" sign stability. This talk is based on joint work with Tsukasa Ishibashi.
