Theorem lmconst 15073

Description: A constant sequence converges to its value. (Contributed by NM, 8-Nov-2007.) (Revised by Mario Carneiro, 14-Nov-2013.)

Hypothesis

Ref	Expression
lmconst.2	|- Z = ( ZZ>= ` M )

Assertion

Ref	Expression
lmconst	|- ( ( J e. (TopOn ` X ) /\ P e. X /\ M e. ZZ ) -> ( Z X. { P } ) ( ~~> t ` J ) P )

Proof of Theorem lmconst

Dummy variables j k u are mutually distinct and distinct from all other variables.
