Theorem lmfpm 14993
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(⇝𝑡𝐽)𝑃) → 𝐹 ∈ (𝑋pm ℂ))

Proof of Theorem lmfpm
Dummy variables 𝑦 𝑢 are mutually distinct and distinct from all other variables.
