Khovanov-Lauda-Rouquier subalgebras and redotted Webster algebras

Abstract

We define Khovanov-Lauda-Rouquier subalgebras which are generalizations of redotted versions of Webster's tensor product algebras of type $A_1$. Quotient algebras of these subalgebras are isomorphic to Webster's tensor product algebras in general type.
