The colored-link motivic–DAHA embedding conjecture

Let R=Fq[[x,y]]Ω=Fq[[ϵj,ζj]]\mathcal{R}=\mathbf{F}_q[[x,y]]\subset\Omega=\mathbf{F}_q[[\epsilon_j,\zeta_j]], and let R~=Fq[[x~,y~]]\widetilde{\mathcal R}=\mathbf{F}_q[[\widetilde x,\widetilde y]] be the sufficiently general deformation with x~=j=1τπjχj\widetilde x=\sum_{j=1}^{\tau}\pi_j\chi_j and y~=y\widetilde y=y. Suppose σ=(c1cκ)\sigma=(c_1\ge\cdots\ge c_\kappa). Colored-link embedding conjecture. The standard modules for R\mathcal R can be identified with standard modules for R~\widetilde{\mathcal R} whose componentwise spans satisfy OiM~=Ωi\mathcal O_i\widetilde M=\Omega_i, and under this identification

j=1c11(1+aqj)Hσmot\prod_{j=1}^{c_1-1}(1+aq^j)\,\mathcal H^{mot}_\sigma

is naturally embedded in the motivic superpolynomial H~\widetilde{\mathcal H} of R~\widetilde{\mathcal R}.
