Theorem lmfpm 15095

Description: If 𝐹 converges, then 𝐹 is a partial function. (Contributed by Mario Carneiro, 23-Dec-2013.)

Assertion

Ref	Expression
lmfpm	⊢ ((𝐽 ∈ (TopOn‘𝑋) ∧ 𝐹(⇝𝑡‘𝐽)𝑃) → 𝐹 ∈ (𝑋 ↑pm ℂ))

Proof of Theorem lmfpm

Dummy variables 𝑦 𝑢 are mutually distinct and distinct from all other variables.
