Any 3 manifold with torus boundary admits either no L-space Dehn filling, a unique L-space filling, or an interval of L-space fillings. In the latter case, which we call ``Floer simple,’’ we construct an invariant which computes the interval of L-space filling slopes from the Turaev torsion and a given slope from the interval’s interior. This tool allows us to recharacterize the set of L-space Seifert-fibered spaces, and to prove a conjecture of Boyer and Clay about L-spaces formed from gluing 3-manifolds along a torus. This is joint work with Jake Rasmussen.
