Description: If  F converges, then  F is a partial function. (Contributed by Mario Carneiro, 23-Dec-2013.)
Assertion
Ref Expression
lmfpm  |-  ( ( J  e.  (TopOn `  X )  /\  F
( ~~> t `  J
) P )  ->  F  e.  ( X  ^pm  CC ) )

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