Earrings, sutures and pointed links
arXiv:1809.09254
Abstract
We prove a rank inequality on the instanton knot homology and the Khovanov homology of a link in . The key step of the proof is to construct a spectral sequence relating Baldwin-Levine-Sarkar's pointed Khovanov homology to a singular instanton invariant for pointed links.
