**Hence**y * ( Tr ) / < € , so that Tx e N ( 0 ; yi , ... , Y * , £ ) . Therefore , T is weaklycontinuous at the origin , and

**hence**at every point . Conversely , suppose that Tis weakly continuous , and y * € Y * . Then y * T is a linear functional on X which is

Put K ; = co ( ( Titu ) nQ ) C9i + U . Then Ki is a closed , and

**hence**a compact ,subset of co ( Q ) .

**Hence**co ( Q ) = Co ( K , U ... UK ) = co ( KU ... UK , ) , by aneasy induction on Lemma 2.5 . It follows readily that p has the form p = < ! - 1 a ; k
