Description: Value of the second Chebyshev function, or summary von Mangoldt function. (Contributed by Mario Carneiro, 7-Apr-2016.)

Assertion

Ref	Expression
chpval	⊢ (𝐴 ∈ ℝ → (ψ‘𝐴) = Σ𝑛 ∈ (1...(⌊‘𝐴))(Λ‘𝑛))

Distinct variable group:   𝐴,𝑛

Proof of Theorem chpval

Dummy variable 𝑥 is distinct from all other variables.
