**norm**is the**norm**of the pair [ 1 , T / ] as an element of the graph of T. ( 1 ) . Now T ( T ) is an adjoint ( Theorem 10 ) ; therefore ( cf. XII.1.6 ) D ( T_ ( T ) ) is complete in the**norm**tla . Since the two additional terms ...Page 1431

**norm**makes each of the spaces listed above into a complete F - space . If k < oo and I is compact , but not otherwise , the spaces C * ( 1 ) and C ( I ) are B - spaces under a**norm**equivalent to the**norm**displayed ...### What people are saying - Write a review
