Description: Lemma for cvmlift . Putting the results of cvmliftlem11 , cvmliftlem13 and cvmliftmo together, we have that K is a continuous function, satisfies F o. K = G and K ( 0 ) = P , and is equal to any other function which also has these properties, so it follows that K is the unique lift of G . (Contributed by Mario Carneiro, 16-Feb-2015)
