Theorem itg2monolem1

Description: Lemma for itg2mono . We show that for any constant t less than one, t x. S.1 H is less than S , and so S.1 H <_ S , which is one half of the equality in itg2mono . Consider the sequence A ( n ) = { x | t x. H <_ F ( n ) } . This is an increasing sequence of measurable sets whose union is RR , and so ` H |`A ( n ) has an integral which equals S.1 H in the limit, by itg1climres . Then by taking the limit in ` ( t x. H ) |`A ( n ) <_ F ( n ) , we get t x. S.1 H <_ S as desired. (Contributed by Mario Carneiro, 16-Aug-2014) (Revised by Mario Carneiro, 23-Aug-2014)
