Theorem brabga 4358

Description: The law of concretion for a binary relation. (Contributed by Mario Carneiro, 19-Dec-2013.)

Hypotheses

Ref	Expression
opelopabga.1	|- ( ( x = A /\ y = B ) -> ( ph <-> ps ) )
brabga.2	|- R = { <. x , y >. | ph }

Assertion

Ref	Expression
brabga	|- ( ( A e. V /\ B e. W ) -> ( A R B <-> ps ) )

Distinct variable groups:   x, y, A   x, B, y   ps, x, y

Allowed substitution hints:   ph( x, y)   R( x, y)   V( x, y)   W( x, y)
