Description: Reverse closure for an even covering. (Contributed by Mario Carneiro, 11-Feb-2015.)

Hypothesis

Ref	Expression
cvmcov.1	|- S = ( k e. J |-> { s e. ( ~P C \ { (/) } ) | ( U. s = ( `' F " k ) /\ A. u e. s ( A. v e. ( s \ { u } ) ( u i^i v ) = (/) /\ ( F |` u ) e. ( ( C ↾t u ) Homeo ( J ↾t k ) ) ) ) } )

Assertion

Ref	Expression
cvmsrcl	|- ( T e. ( S ` U ) -> U e. J )

Distinct variable groups:   k, s, u, v, C   k, F, s, u, v   k, J, s, u, v   U, k, s, u, v   T, s, u, v

Allowed substitution hints:   S( v, u, k, s)   T( k)
