穿孔环面拟fuchs空间的线性切片

Linear slices of the quasifuchsian space of punctured tori

Yohei Komori, Yasushi Yamashita

摘要:

在固定了拟复收缩环面群G的标记(V,W)之后,复长度l_V和复扭曲τ_V、W参数定义了收缩环面的拟复空间QF到C^2的全纯嵌入。它被称为QF的复数Fenchel-Nielsen坐标。对于复数c,设Q_gamma,c是由线性方程l_V=c定义的C^2的仿射子空间。然后,我们可以考虑QF的线性切片L由QF \cap Q_gamma,c,这是QF的全纯切片。对于任何正实值c,L总是包含所谓的Bers-Maskit切片BM_gamma,c。本文证明了当c充分小时,L与BM_gamma,c重合,而当c充分大时,L除了BM_gamma,c外还有其它分量.我们还观察到L的标度性质。

英文摘要:

After fixing a marking (V, W) of a quasifuchsian punctured torus group G, the complex length l_V and the complex twist tau_V,W parameters define a holomorphic embedding of the quasifuchsian space QF of punctured tori into C^2. It is called the complex Fenchel-Nielsen coordinates of QF. For a complex number c, let Q_gamma,c be the affine subspace of C^2 defined by the linear equation l_V=c. Then we can consider the linear slice L of QF by QF \cap Q_gamma,c which is a holomorphic slice of QF. For any positive real value c, L always contains the so called Bers-Maskit slice BM_gamma,c. In this paper we show that if c is sufficiently small, then L coincides with BM_gamma,c whereas L has other components besides BM_gamma,c when c is sufficiently large. We also observe the scaling property of L.
