圆上纤维的几何可分性和三维流形

Geometric inflexibility and 3-manifolds that fiber over the circle

Jeffrey Brock, Kenneth Bromberg

摘要:

我们证明了双曲3-流形是几何刚性的:Kleinian群的单位拟共形变形扩展到同分点之间的等变双Lipschitz同构,其逐点双Lipschitz常数在距离凸核边界的距离上指数衰减。在薄的部分的点的估计是由类似的估计短曲线的复杂的长度。利用这一性质给出了伪Anosov双重迭代在闭曲面的拟Fuchsian空间上收敛的一个新的证明,并由此得到了在圆上具有伪Anosov单值的闭三维流形的双曲化定理.

英文摘要:

We prove hyperbolic 3-manifolds are geometrically inflexible: a unit quasiconformal deformation of a Kleinian group extends to an equivariant bi-Lipschitz diffeomorphism between quotients whose pointwise bi-Lipschitz constant decays exponentially in the distance form the boundary of the convex core for points in the thick part. Estimates at points in the thin part are controlled by similar estimates on the complex lengths of short curves. We use this inflexibility to give a new proof of the convergence of pseudo-Anosov double-iteration on the quasi-Fuchsian space of a closed surface, and the resulting hyperbolization theorem for closed 3-manifolds that fiber over the circle with pseudo-Anosov monodromy.
