摘要：
We prove that, for a hyperbolic two-bridge knot, infinitely many Dehn fillings are rigid in SO(0)(4, 1). Here rigidity means that any discrete and faithful representation in SO(0)(4, 1) is conjugate to the holonomy representation in SO(0)(3, 1). We also show local rigidity for almost all Dehn fillings.
