“…Partially motivated by the construction in [QS16], a deformation W = W (n, 1) of A ! n was considered in [KS18] and the authors showed that there is a categorical braid group action on the homotopy category of W -modules. This result was extended in [KLSY18] to a categorical braid group action on the homotopy category of a deformation of more general Webster algebras for sl 2 , for which W is a special case (hence the notation).…”

We construct a 2-representation categorifying the symmetric Howe representation of gl m using a deformation of an algebra introduced by Webster. As a consequence, we obtain a categorical braid group action taking values in a homotopy category.
We define Khovanov-Lauda-Rouquier subalgebras which are generalizations of redotted versions of Webster's tensor product algebras of type A 1 defined in [KLSY18]. Quotient algebras of these subalgebras are isomorphic to Webster's tensor product algebras in general type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
