Let \(S\) be a Noetherian separated scheme of finite Krull dimension, and \(\mathcal {SH}(S)\) be the motivic stable homotopy category of Morel-Voevodsky. In order to get a motivic analogue of the Postnikov tower, Voevodsky (MR 1977582) constructs the slice filtration by filtering \(\mathcal {SH}(S)\) with respect to the smash powers of the multiplicative group \(\mathbb G_{m}\).

The author shows that the slice filtration is compatible with the smash product in Jardine's category \(\mathrm {Spt}_{T}^{\Sigma }\mathcal {M}_{\ast}\) of motivic symmetric \(T\)-spectra (MR 1787949) and describes several interesting consequences that follow from this compatibility. Among the consequences that follow from this compatibility is that over a perfect field all the slices \(s_{q}\) are in a canonical way modules in \(\mathrm {Spt}_{T}^{\Sigma }\mathcal {M}_{\ast }\) over the motivic Eilenberg-MacLane spectrum \(H\mathbb Z\), and if the field has characteristic zero it follows that the slices \(s_{q}\) are big motives in the sense of Voevodsky. This relies on the work of Levine (MR 2365658), Röndigs-Østvær (MR 2435654), and Voevodsky (MR 2101286). It also follows that the smash product in \(\mathrm {Spt}_{T}^{\Sigma }\mathcal {M}_{\ast }\) induces pairings in the motivic Atiyah-Hirzebruch spectral sequence.
