If T is

If T is

**weakly compact**, then TS is compact in the Y * topology of Y and thus z ( TS ) is compact and hence closed in the Y * topology of Y ** . Thus if T is**weakly compact**, ( i ) yields T ** ( S ) C x ( TS ) .Page 494

From IV.10.2 we conclude that T * maps the unit sphere of X * into a conditionally

**weakly compact**set of rca ( S ) ... If T is a**weakly compact**operator from C ( S ) to X , then T sends weak Cauchy sequences into strongly convergent ...Page 507

Let ( S , E , u ) be a o - finite positive measure space , and let T be a

Let ( S , E , u ) be a o - finite positive measure space , and let T be a

**weakly compact**operator on L ( S , E , u ) to a separable subset of the B - space X. Then there exists a u - essentially unique bounded measurable function ...### What people are saying - Write a review
