An Example of Homomorphisms from Guay’s Affine Yangians to Non-rectangular W-algebras
We construct a non-trivial homomorphism from the Guay’s affine Yangian associated with \(\widehat{\mathfrak {sl}}(n)\) to the universal enveloping algebra of the W-algebra associated with a Lie algebra \(\mathfrak {gl}(m+n)\) and a nilpotent element of type \((2^{n},1^{m-n})\) for \(m>n\).
