Description: Basic inner product property of a unitary operator. (Contributed by NM, 22-Jan-2006.) (New usage is discouraged.)

Assertion

Ref	Expression
unop	|- ( ( T e. UniOp /\ A e. ~H /\ B e. ~H ) -> ( ( T ` A ) .ih ( T ` B ) ) = ( A .ih B ) )

Proof of Theorem unop

Dummy variables x y are mutually distinct and distinct from all other variables.
