Theorem sge0isum 45143

Description: If a series of nonnegative reals is convergent, then it agrees with the generalized sum of nonnegative extended reals. (Contributed by Glauco Siliprandi, 11-Oct-2020.)

Ref	Expression
sge0isum.m	⊢ (𝜑 → 𝑀 ∈ ℤ)
sge0isum.z	⊢ 𝑍 = (ℤ_≥‘𝑀)
sge0isum.f	⊢ (𝜑 → 𝐹:𝑍⟶(0[,)+∞))
sge0isum.g	⊢ 𝐺 = seq𝑀( + , 𝐹)
sge0isum.gcnv	⊢ (𝜑 → 𝐺 ⇝ 𝐵)

**Assertion**
Ref	Expression
sge0isum	⊢ (𝜑 → (Σ^{^}‘𝐹) = 𝐵)

Proof of Theorem sge0isum Dummy variables 𝑖 𝑗 𝑘 𝑥 𝑦 𝑧 are mutually distinct and distinct from all other variables.
