We investigate certain periodic phenomena in the classical Adams spectral sequence which are related to the polynomial generators υn in π∗(ΒΡ). We define the notion of a class α in ExtΑ(Ζ/2,Ζ/2) being υn-periodic or υn-torsion and prove that classes that are υn-torsion are also υκ-torsion for all κ such that 0 ≤ κ ≤ n. This allows us to define a chromatic filtration of ExtΑ(Ζ/2,Ζ/2) paralleling the chromatic filtration of the Novikov spectral sequence Ε2-term given in .
