Theorem psercn2 24729

Description: Since by pserulm 24728 the series converges uniformly, it is also continuous by ulmcn 24705. (Contributed by Mario Carneiro, 3-Mar-2015.)

**Hypotheses**
Ref	Expression
pserf.g	⊢ 𝐺 = (𝑥 ∈ ℂ ↦ (𝑛 ∈ ℕ₀ ↦ ((𝐴‘𝑛) · (𝑥↑𝑛))))
pserf.f	⊢ 𝐹 = (𝑦 ∈ 𝑆 ↦ Σ𝑗 ∈ ℕ₀ ((𝐺‘𝑦)‘𝑗))
pserf.a	⊢ (𝜑 → 𝐴:ℕ₀⟶ℂ)
pserf.r	⊢ 𝑅 = sup({𝑟 ∈ ℝ ∣ seq0( + , (𝐺‘𝑟)) ∈ dom ⇝ }, ℝ^*, < )
pserulm.h	⊢ 𝐻 = (𝑖 ∈ ℕ₀ ↦ (𝑦 ∈ 𝑆 ↦ (seq0( + , (𝐺‘𝑦))‘𝑖)))
pserulm.m	⊢ (𝜑 → 𝑀 ∈ ℝ)
pserulm.l	⊢ (𝜑 → 𝑀 < 𝑅)
pserulm.y	⊢ (𝜑 → 𝑆 ⊆ (^◡abs “ (0[,]𝑀)))

**Assertion**
Ref	Expression
psercn2	⊢ (𝜑 → 𝐹 ∈ (𝑆–cn→ℂ))
