Theorem cnmpt1ip 23521

Description: Continuity of inner product; analogue of cnmpt12f 21946 which cannot be used directly because ·_𝑖 is not a function. (Contributed by Mario Carneiro, 13-Oct-2015.)

**Hypotheses**
Ref	Expression
cnmpt1ip.j	⊢ 𝐽 = (TopOpen‘𝑊)
cnmpt1ip.c	⊢ 𝐶 = (TopOpen‘ℂ_fld)
cnmpt1ip.h	⊢ , = (·_𝑖‘𝑊)
cnmpt1ip.r	⊢ (𝜑 → 𝑊 ∈ ℂPreHil)
cnmpt1ip.k	⊢ (𝜑 → 𝐾 ∈ (TopOn‘𝑋))
cnmpt1ip.a	⊢ (𝜑 → (𝑥 ∈ 𝑋 ↦ 𝐴) ∈ (𝐾 Cn 𝐽))
cnmpt1ip.b	⊢ (𝜑 → (𝑥 ∈ 𝑋 ↦ 𝐵) ∈ (𝐾 Cn 𝐽))

**Assertion**
Ref	Expression
cnmpt1ip	⊢ (𝜑 → (𝑥 ∈ 𝑋 ↦ (𝐴 , 𝐵)) ∈ (𝐾 Cn 𝐶))
