摘要:设 ψεMod(S) 为曲面 S 的映射类群的元素。我们对 Bers 切片中的准 Fuchsian 双曲 3-流形序列 {Q(phiiX,Y)}i=1∞ 的代数和几何极限进行分类。当 ψ 具有无限阶且有有限阶限制时,存在本质的次曲面 Dψ⊂S,使得几何极限具有同胚类型 S×ℝ-Dψ×{0}。通常, ψ 具有伪阿诺索夫限制,并且 D ψ 具有负欧拉特性的分量;这些分量对应于几何极限的新渐近周期性简单简并端。我们证明存在 s≥1 取决于 phi 并以 S 为界,因此 {Q(phisiX,Y)}i=1∞ 在代数和几何上收敛,并且我们给出了明确的极限准等距模型。
Abstract.Let ϕ∈Mod(S) be an element of the mapping class group of a surface S. We classify algebraic and geometric limits of sequences {Q(ϕiX,Y)}i=1∞ of quasi-Fuchsian hyperbolic 3-manifolds ranging in a Bers slice. When ϕ has infinite order with finite-order restrictions, there is an essential subsurface Dϕ⊂S so that the geometric limits have homeomorphism type S×ℝ-Dϕ×{0}. Typically, ϕ has pseudo-Anosov restrictions, and Dϕ has components with negative Euler characteristic; these components correspond to new asymptotically periodic simply degenerate ends of the geometric limit. We show there is an s≥1 depending on ϕ and bounded in terms of S so that {Q(ϕsiX,Y)}i=1∞ converges algebraically and geometrically, and we give explicit quasi-isometric models for the limits.
