"Several detection results of Khovanov homology on links"

Khovanov homology is a combinatorially defined invariant for knots and links.  The detection properties of Khovanov homology has been a focus of study since the introduction of the theory.  In this talk, I will present several new detection results of Khovanov homology on links.  In particular, I will discuss a result that classifies all links with minimal Khovanov homology, which answered a question asked by Batson-Seed and generalized the unlink detection theorem of Hedden-Ni and Batson-Seed.  This talk is based on joint works with Yi Xie and Zhenkun Li.
