报告摘要：
It is well known that the complex hyperbolic triangle group G of (3,3,4)-type generated by three complex reflections has a one-dimensional moduli space. We show there is an open set U of the 3-sphere, such that the quotient space of the open set U by the group G is always the figure-eight knot complement during the deformation process,thereby confirming a conjecture of Falbel, Guilloux, and Will. This is joint work with Baohua Xie.
