L-space surgeries on satellites by algebraic links

Abstract

Given an $n$-component link $L$ in any 3-manifold $M$, the space $\mathcal{L}\subset (\mathbb{Q}\cup \{\infty \}{)}^n$ of rational surgery slopes yielding L-spaces is already fully characterized (in joint work by the author) when $n=1$ and $\mathcal{L}$ is nontrivial. For $n>1$, however, there are no previous results for $\mathcal{L}$ as a rational subspace, and only limited results for integer surgeries $\mathcal{L}\cap {\mathbb{Z}}^n$ on $S^3$. Herein, we provide the first nontrivial explicit descriptions of $\mathcal{L}$ for rational surgeries on multi-component links. Generalizing Hedden's and Hom's L-space result for cables, we compute both $\mathcal{L}$, and its topology, for all satellites by torus-links in $S^3$. For fractal-boundaried $\mathcal{L}$ resulting from satellites by algebraic links or iterated torus links, we develop arbitrarily precise approximation tools. We also extend the provisional validity of the L-space conjecture for rational surgeries on a knot $K\subset S^3$ to rational surgeries on such satellite-links of $K$. These results exploit the author's generalized Jankins-Neumann formula for graph manifolds.
