$\mathfrak{gl}_1$的两个仿射杨格曲面的胶合

Gluing two affine Yangians of $\mathfrak{gl}_1$

Wei Li, Pietro Longhi

摘要:

通过将$\mathfrak{gl}_1$的仿射Yangian的两个拷贝粘在一起,构造了一类四参数仿射Yangian代数。我们的构造允许胶合运营商与任意(整数或半整数)共形尺寸和任意(玻色子或费米子)统计,这是相关的相对框架。由此产生的代数族是$\mathcal{N}=2$仿射杨代数的双参数推广,它同构于$\mathfrak{u}(1)\oplus \mathcal{W}^{\mathcal{N}=2}_{\infty}[λ]$的泛包络代数。我们构造的所有代数都有“孪生平面分区”的自然表示,孪生平面分区是沿着一条公共腿适当连接的一对平面分区。我们观察到,几何的孪生平面分区,这决定了代数,承担惊人的相似之处,某些复曲面卡-丘三倍的几何。

英文摘要:

We construct a four-parameter family of affine Yangian algebras by gluing two copies of the affine Yangian of $\mathfrak{gl}_1$. Our construction allows for gluing operators with arbitrary (integer or half integer) conformal dimension and arbitrary (bosonic or fermionic) statistics, which is related to the relative framing. The resulting family of algebras is a two-parameter generalization of the $\mathcal{N}=2$ affine Yangian, which is isomorphic to the universal enveloping algebra of $\mathfrak{u}(1)\oplus \mathcal{W}^{\mathcal{N}=2}_{\infty}[λ]$. All algebras that we construct have natural representations in terms of "twin plane partitions", a pair of plane partitions appropriately joined along one common leg. We observe that the geometry of twin plane partitions, which determines the algebra, bears striking similarities to the geometry of certain toric Calabi-Yau threefolds.
