In this note we prove that the intersections of the levels of the dimension filtration on Voevodsky’s motivic complexes over a field with the levels of the slice filtration are “as small as possible”. This statement is applied to prove that a conjecture of Ayoub is equivalent to a certain orthogonality assumption.
