Theorem f1oiso2 5500

Description: Any one-to-one onto function determines an isomorphism with an induced relation S. (Contributed by Mario Carneiro, 9-Mar-2013.)

Hypothesis

Ref	Expression
f1oiso2.1	|- S = {<.x, y>. | ((x e. B /\ y e. B) /\ (`'H` x)R(`'H` y))}

Assertion

Ref	Expression
f1oiso2	|- (H:A-1-1-onto->B -> H Isom R, S (A, B))

Distinct variable groups:   x,A,y   x,B,y   x,H,y   x,R,y

Allowed substitution hints:   S(x,y)

Proof of Theorem f1oiso2

Dummy variables w z are mutually distinct and distinct from all other variables.
