Theorem mulogsum 25673

Description: Asymptotic formula for Σ𝑛 ≤ 𝑥, (μ(𝑛) / 𝑛)log(𝑥 / 𝑛) = 𝑂(1). Equation 10.2.6 of [Shapiro], p. 406. (Contributed by Mario Carneiro, 14-May-2016.)

**Assertion**
Ref	Expression
mulogsum	⊢ (𝑥 ∈ ℝ⁺ ↦ Σ𝑛 ∈ (1...(⌊‘𝑥))(((μ‘𝑛) / 𝑛) · (log‘(𝑥 / 𝑛)))) ∈ 𝑂(1)

Distinct variable group: 𝑥,𝑛

Proof of Theorem mulogsum Dummy variables 𝑘 𝑚 𝑦 are mutually distinct and distinct from all other variables.
