Out(F_r)II中的理想Whitehead图:每秩的完全图

Ideal Whitehead Graphs in Out(F_r) II: The Complete Graph in Each Rank

Catherine Pfaff

摘要:

我们将展示如何构建,为每个$r \geq 3$,年龄,完全不可约的$ϕ\in Out(F_r)$的理想Whitehead图是完全图的$2r-1$顶点。本文是第二次在一系列的三个,我们表明,正是18的21个连接,单纯,五顶点图是理想的Whitehead图完全不可约$ϕ\in Out(F_3)$。其结果是第一步的$Out(F_r)$版本的Masur-Smillie定理证明,正是这些指标清单产生的奇异测量叶状伪Anosov映射类。本文还给出了求周期Nielsen路的一种方法,并证明了一个判别几何上完全不可约的$ϕ\in Out(F_r)$的准则

英文摘要:

We show how to construct, for each $r \geq 3$, an ageometric, fully irreducible $ϕ\in Out(F_r)$ whose ideal Whitehead graph is the complete graph on $2r-1$ vertices. This paper is the second in a series of three where we show that precisely eighteen of the twenty-one connected, simplicial, five-vertex graphs are ideal Whitehead graphs of fully irreducible $ϕ\in Out(F_3)$. The result is a first step to an $Out(F_r)$ version of the Masur-Smillie theorem proving precisely which index lists arise from singular measured foliations for pseudo-Anosov mapping classes. In this paper we additionally give a method for finding periodic Nielsen paths and prove a criterion for identifying representatives of ageometric, fully irreducible $ϕ\in Out(F_r)$
