suplocexpr.m	|- ( ph -> E. x x e. A )
suplocexpr.ub	|- ( ph -> E. x e. P. A. y e. A y <P x )
suplocexpr.loc	|- ( ph -> A. x e. P. A. y e. P. ( x <P y -> ( E. z e. A x <P z \/ A. z e. A z <P y ) ) )

Assertion

Ref	Expression
suplocexprlemdisj	|- ( ph -> A. q e. Q. -. ( q e. U. ( 1st " A ) /\ q e. ( 2nd ` B ) ) )

Distinct variable groups:   w, A, u   x, A, y   w, B   ph, q, w   ph, x, y   u, q

Allowed substitution hints:   ph( z, u)   A( z, q)   B( x, y, z, u, q)

Proof of Theorem suplocexprlemdisj

Dummy variables s t are mutually distinct and distinct from all other variables.
