L-space surgeries on 2-component L-space links

Abstract

In this paper, we analyze L-space surgeries on two component L-space links. We show that if one surgery coefficient is negative for the L-space surgery, then the corresponding link component is an unknot. If the link admits very negative (i.e. d1,d20d_{1}, d_{2}\ll0) L-space surgeries, it is the Hopf link. We also give a way to characterize the torus link T(2,2l)T(2, 2l) by observing an L-space surgery Sd1,d23(L)S^{3}_{d_{1}, d_{2}}(\mathcal{L}) with d1d2<0d_{1}d_{2}<0 on a 2-component L-space link with unknotted components. For some 2-component L-space links, we give explicit descriptions of the L-space surgery sets.
