**converges**, we see from the continuity of F that > Х m.no O lim lĂr ( s ) — 1 ( ) 2 ds = 0 , which implies ( III.3.6 ) that Ăn**converges**in measure on o . Conversely , if ( 29 ) and ( 30 ) ...Page 2218

It must be shown that { E , }

**converges**strongly to E. By Lemma 6 , E is in B and so a consideration of the sequence { E. -E } shows that it may be assumed that E 0. Thus , to make an indirect proof , it is assumed that the sequence ...Page 2462

Moreover , if C belongs to the trace class C1 , then T , C

Moreover , if C belongs to the trace class C1 , then T , C

**converges**to zero in trace norm , and CT ***converges**to zero in trace norm . PROOF . The set K = C ( { xe H || 2 < 1 } ) is conditionally compact , and thus for each ε > 0 there ...### What people are saying - Write a review
