Let S(σ,t)=1πargζ(σ+it) be the argument of the Riemann zeta-function at the point σ+it in the critical strip. For n1 and t>0, we defineSn(σ,t)=0tSn1(σ,τ)dτ+δn,σ, where δn,σ is a specific constant depending on σ and n. Let 0β<1 be a fixed real number. Assuming the Riemann hypothesis, we establish lower bounds for the maximum of Sn(σ,t+h)Sn(σ,t) near the critical line, on the interval TβtT and in a small range of h. This improves some results of the first author and generalizes a result of the authors on S(t). We also give new omega results for Sn(t), improving a result by Selberg.
