Abstract

We show that sutured embedded contact homology is a natural invariant of sutured contact $3$-manifolds which can potentially detect some of the topology of the space of contact structures on a $3$-manifold with boundary. The appendix, by C. H. Taubes, proves a compactness result for the completion of a sutured contact $3$-manifold in the context of Seiberg–Witten Floer homology, which enables us to complete the proof of naturality.
