Qiuyu Ren - Gluing formulas for Khovanov skein lasagna modules, & detection of exotic 4-manifolds
Institute for Pure & Applied Mathematics (IPAM) · 78:04
The talk extends the Khovanov skein lasagna module, an invariant of 4-manifolds, with gluing formulas, a vanishing theorem and a non-vanishing theorem. These are used to show that the −1-traces on the mirror of the kn...
