Abstract

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 $m>n$.

从 Guay 的 Affine Yanians 到非矩形 W-gebras 的同构实例

我们构建了一个从与$\widehat\mathfrak {sl}}(n)$ 相关的盖氏仿射扬基到与$\mathfrak {gl}(m+n)$ 相关的列代数的 W-algebra 的普遍包络代数以及对于$m>.)而言的\((2^{n},1^{m-n})$类型的无穷元的非三重同态；n\).
