对于穿孔表面上的映射类,我们证明了伪anosov性质等价于[IK19]中引入的符号稳定性。特别地,我们得出了由伪anosov映射类给出的突变循环引起的$mathcal{A}$-和$mathcal{X}$-簇变换的代数熵与它的拓扑熵一致的结论。
For a mapping class on a punctured surface, we prove that the pseudo-Anosov property is equivalent to the sign stability introduced in [IK19]. In particular we conclude that the algebraic entropies of the $mathcal{A}$- and $mathcal{X}$-cluster transformations induced by a mutation loop given by a pseudo-Anosov mapping class both coincide with its topological entropy.
