... weakly compact , then TS is compact in the Y * topology of Y and thus x ( TS ) is compact and hence closed in the * topology of ** . Thus if T is weakly compact , ( i ) yields T ** ( S1 ) ( TS ) . According to Theorem V.4.5 , S1 = S ...

... Weakly compact operators from C [ 0 , 1 ] to X were treated by Sirvint [ 3 ] . A very incisive discussion of weakly compact operators with domain C ( S ) was given by Grothendieck [ 4 ] who proved Theorems 7.4-7.6 by other means ...
