论文摘要
在所有双帝国数字中，我们表征了所有的galois共轭物是真实的或单形的，那些承认能力是伪anosov同构的力量，这是由瑟斯顿的结构引起的。反过来，这相当于承认是两部分Coxeter转换的光谱半径的功率。
Among all bi-Perron numbers, we characterise those all of whose Galois conjugates are real or unimodular as the ones that admit a power which is the stretch factor of a pseudo-Anosov homeomorphism arising from Thurston's construction. This is in turn equivalent to admitting a power which is the spectral radius of a bipartite Coxeter transformation.
