The standard and costandard module conjecture for non-symmetric quantum loop groups

About 3 years old · traced to

For each w∈NI∙w\in\mathbb{N} I^\bullet, let WW be the corresponding framing data, and let M~∙(W)\widetilde{\mathfrak{M}}^\bullet(W) be the associated moduli space with potential f~1∙\widetilde{f}^\bullet_1. Write K(M~∙(W),f~1∙)K(\widetilde{\mathfrak{M}}^\bullet(W),\widetilde{f}^\bullet_1) for its critical K-theory module and K(M~∙(W),f~1∙)L~∙(W)K(\widetilde{\mathfrak{M}}^\bullet(W),\widetilde{f}^\bullet_1)_{\widetilde{\mathfrak{L}}^\bullet(W)} for the corresponding module supported on L~∙(W)\widetilde{\mathfrak{L}}^\bullet(W). Standard and costandard module conjecture. For each w∈NI∙w\in\mathbb{N} I^\bullet, the $\mathrm{U}_\zeta(\mathrm{L}\mathfrak{g})$-modules

K(M~∙(W),f~1∙),K(M~∙(W),f~1∙)L~∙(W)K(\widetilde{\mathfrak{M}}^\bullet(W),\widetilde{f}^\bullet_1),\quad K(\widetilde{\mathfrak{M}}^\bullet(W),\widetilde{f}^\bullet_1)_{\widetilde{\mathfrak{L}}^\bullet(W)}

are isomorphic, respectively, to the costandard module and the standard module with ℓ\ell-highest weight Ψw\Psi_w. This conjecture identifies the critical K-theory modules constructed from the moduli spaces with the standard and costandard representations of the non-symmetric quantum loop group; the supplied text gives no resolution, so its status is open.
