Let ρ(x)=x[x], χ=χ(0,1), λ(x)=χ(x)logx, and M(x)=ΣKxμ(k), where μ is the Möbius function. Norms are in Lp(0,), 1<p<. For M1(θ)=M(1/θ) it is noted that ξ(s)0 in s>1/p is equivalent to M1r< for all r(1,p). The space is the linear space generated by the functions xρ(θ/x) with θ(0,1]. Define Gn(x)=1/n1M1(θ)ρ(θ/x)θ1dθ. For all p(1,) we prove the following theorems: (I) M1p< implies λ¯Lp, and λ¯Lp implies M1r< for all r(1,p). (II) Gnλp0 implies ξ(s)0 in s1/p, and ξ(s)0 in s1/p implies Gnλr0 for all r(1,p).
