Guay's affine Yangians and non-rectangular $W$-algebras (2301.00035v2)
Published 30 Dec 2022 in math.QA
Abstract: We construct a non-trivial homomorphism from the Guay's affine Yangian to the universal enveloping algebra of non-rectangular $W$-algebras of type $A$. In order to construct the homomorphism, we extend the Guay's affine Yangian and its coproduct.
