Principal Subspaces for Double Yangian DY(sl2)
Journal of Lie Theory, Volume 28 (2018) no. 3, pp. 673-694
We consider the realization of level $1$ infinite-dimensional modules for the double Yangian DY$({\frak s}{\frak l}_2)$ found by K. Iohara. We use the corresponding vertex operators to generate a family of nonlocal $h$-vertex algebras $W_N$, $N\in\mathbb{Z}_{\ge0}$. Finally, we construct combinatorial bases of $W_N$ and establish a connection with the sum side of the Rogers-Ramanujan identity.
