Description: Reverse closure for an isomorphism of rings. (Contributed by AV, 22-Oct-2019.)
Assertion
Ref Expression
rimrcl  |-  ( F  e.  ( R RingIso  S
)  ->  ( R  e.  _V  /\  S  e. 
_V ) )

Proof of Theorem rimrcl
Dummy variables  f  r  s are mutually distinct and distinct from all other variables.
