The quasi-isomorphism conjecture for dg-cyclic modules

Let GρNG_{\rho}^{{\underline{N}}} and YρNY_{\rho}^{{\underline{N}}} be the dg-enhanced and ordinary cyclic modules constructed from the tensor-product data, with differential dNd_N on GρNG_{\rho}^{{\underline{N}}}. Quasi-isomorphism conjecture. There is a quasi-isomorphism

(GρN,dN)(YρN,0).(G_{\rho}^{{\underline{N}}},d_N)\xrightarrow{\simeq}(Y_{\rho}^{{\underline{N}}},0).

This conjecture asserts that the differential enhancement recovers the corresponding ordinary cyclic module up to quasi-isomorphism; the supplied text gives no resolution status.
