Theorem fsumcn 22481

Description: A finite sum of functions to complex numbers from a common topological space is continuous. The class expression for 𝐵 normally contains free variables 𝑘 and 𝑥 to index it. (Contributed by NM, 8-Aug-2007.) (Revised by Mario Carneiro, 23-Aug-2014.)

**Hypotheses**
Ref	Expression
fsumcn.3	⊢ 𝐾 = (TopOpen‘ℂ_fld)
fsumcn.4	⊢ (𝜑 → 𝐽 ∈ (TopOn‘𝑋))
fsumcn.5	⊢ (𝜑 → 𝐴 ∈ Fin)
fsumcn.6	⊢ ((𝜑 ∧ 𝑘 ∈ 𝐴) → (𝑥 ∈ 𝑋 ↦ 𝐵) ∈ (𝐽 Cn 𝐾))

**Assertion**
Ref	Expression
fsumcn	⊢ (𝜑 → (𝑥 ∈ 𝑋 ↦ Σ𝑘 ∈ 𝐴 𝐵) ∈ (𝐽 Cn 𝐾))
