Intrinsic Khovanov homology in RP^3, or what I learned from Morrison-Walker-Wedrich

Skein lasagna modules have become a popular tool in the study of 4-dimensional topology. The original paper of Morrison-Walker-Wedrich rather focuses on the theoretical aspects of Khovanov homology. In particular, they improve the functoriality of Khovanov homology from R^3 to S^3, and from parametrized S^3 to unparametrized S^3’s. I’ll explain how to adapt their ideas to study Khovanov homology of links in RP^3. This is joint work with Qiuyu Ren
