The CoHA affine Yangian identification for cyclic quivers

Let $K>2$, and let $Y^{K}$ be the $C[Chbar_1,Chbar_2]$-linear algebra obtained by gluing the two copies of the double deformed current algebra $A^K$ constructed from observables on M2 branes. Let $\mathcal{Y}^{(K),\operatorname{CoHA}}_{\hbar_1,\hbar_2}$ denote the CoHA integral form of the affine Yangian associated with $\mathfrak{gl}(K)$. The CoHA affine Yangian identification. For any $K>2$, there is an isomorphism of algebras

$$Y^{K} \simeq \mathcal{Y}^{(K),\operatorname{CoHA}}_{\hbar_1,\hbar_2}.$$

This is an expected identification between the algebra constructed in the physics literature and the CoHA integral form of the affine Yangian; the supplied source does not give evidence that it has been proved or disproved.
