abstract: In recent work, Aganagic proposed a categorification of quantum link invariants using Lagrangian Floer theory in multiplicative Coulomb branches equipped with a potential. The braid group action arises from monodromy of this potential. We show that in the case g=sl(2), this braid group action agrees with the braid group action constructed by Webster, which proves that Aganagic’s proposal gives … Read More
