dvhfvadd	|- ( ( K e. HL /\ W e. H ) -> .+ = .+b )

Distinct variable groups:   f, g, E   f, H, g   f, K, g   T, f, g   f, W, g

Allowed substitution hints:   D( f, g)   .+ ( f, g)   .+^ ( f, g)   .+b ( f, g)   U( f, g)

Proof of Theorem dvhfvadd

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