Theorem psrbaglesuppg 14685
Description: The support of a dominated bag is smaller than the dominating bag. (Contributed by Mario Carneiro, 29-Dec-2014.)
Hypothesis
Ref Expression
psrbag.d |- D = { f e. ( NN0 ^m I ) | ( `' f " NN ) e. Fin }
Assertion
Ref Expression
psrbaglesuppg |- ( ( I e. V /\ ( F e. D /\ G : I --> NN0 /\ G oR <_ F ) ) -> ( `' G " NN ) C_ ( `' F " NN ) )
Distinct variable groups:   f, F   f, I
Allowed substitution hints:   D( f)   G( f)   V( f)
Proof of Theorem psrbaglesuppg
Dummy variable x is distinct from all other variables.
