New Versions of the Nyman-beurling Criterion for the Riemann Hypothesis

چکیده
Let ρ(x) = x− [x], χ = χ(0,1), λ(x) = χ(x) logx, and M(x) = ∑ k≤x μ(k), where μ is the Möbius function. Norms are in Lp(0,∞), 1 < p < ∞. For M1(θ) = M(1/θ) it is noted that ζ(s) ≠ 0 in s > 1/p is equivalent to ‖M1‖r < ∞ for all r ∈ (1,p). The space is the linear space generated by the functions x ρ(θ/x) with θ ∈ (0,1]. Define Gn(x)= ∫ 1 1/nM1(θ)ρ(θ/x)θ−1dθ. For all p ∈ (1,∞) we prove the two arithmetical versions of the Nyman-Beurling theorem: (I) ‖M1‖p <∞ implies λ∈ Lp , and λ∈ Lp implies ‖M1‖r <∞ for all r ∈ (1,p). (II) ‖Gn−λ‖p → 0 implies ζ(s)≠ 0 in s ≥ 1/p, and ζ(s)≠ 0 in s > 1/p implies ‖Gn−λ‖r → 0 for all r ∈ (1,p).

A Strengthening of the Nyman-beurling Criterion for the Riemann Hypothesis
Let ρ(x) = x − [x], χ = χ (0,1). In L2(0, ∞) consider the subspace B generated by {ρa|a ≥ 1} where ρa(x) := ρ 1 ax. By the Nyman-Beurling criterion the Riemann hypothesis is equivalent to the statement χ ∈ B. For some time it has been conjectured, and proved in this paper, that the Riemann hypothesis is equivalent to the stronger statement that χ ∈ B nat where B nat is the much smaller subspace...

A General Strong Nyman-beurling Criterion for the Riemann Hypothesis
For each f : [0,∞) → C formally consider its co-Poisson or Müntz transform g(x) = ∑ n≥1 f(nx) − 1 x ∫∞ 0 f(t)dt. For certain f ’s with both f, g ∈ L2(0,∞) it is true that the Riemann hypothesis holds if and only if f is in the L2 closure of the vector space generated by the dilations g(kx), k ∈ N. Such is the case for example when f = χ(0,1] where the above statement reduces to the strong Nyman...

. By the NymanBeurling criterion the Riemann hypothesis is equivalent to the statement χ ∈ B. For some time it has been conjectured, and proved in the first version of this paper, posted in arXiv:math.NT/0202141 v2, that the Riemann hypothesis is equivalent to the stronger statement that χ ∈ Bnat where B is the much smaller subspace generated by {ρa|a ∈ N}. This second version differs from the ...
متن کاملOn Nyman, Beurling and Baez-Duarte’s Hilbert space reformulation of the Riemann hypothesis
Abstract. There has been a surge of interest of late in an old result of Nyman and Beurling giving a Hilbert space formulation of the Riemann hypothesis. Many authors have contributed to this circle of ideas, culminating in a beautiful refinement due to Baez-Duarte. The purpose of this little survey is to dis-entangle the resulting web of complications, and reveal the essential simplicity of th...
