Description: If 𝐹 converges, then 𝐹 is a partial function. (Contributed by Mario Carneiro, 23-Dec-2013.)
Assertion
Ref Expression
lmfpm ((𝐽 ∈ (TopOnβ€˜π‘‹) ∧ 𝐹(β‡π‘‘β€˜π½)𝑃) β†’ 𝐹 ∈ (𝑋 ↑pm β„‚))

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