The theory of Coulomb branch algebras, based on work of Braverman, Finkel- berg and Nakajima, has shed new light on many interesting algebras in repre- sentation theory. One of the most notable is the universal enveloping algebra of gln. I’ll explain how this theory shows a close relationship between the characteristic p and characteristic 0 representation of gln and the cylindri- cal and planar KLRW algebras, in particular, giving a new, combinatorial description of the non-commutative Springer resolution of type A.
