Dual Space and Isometrically Isomorphic Spaces
Not what you're looking for?
Let c be the set of all sequences *see attachment* , such that limit alpha_n exists.
Let be the dual space of c , and c consist of all functions f -> F, F or such that for every e>0 {n E : |f(n)| >E} is finite.
Show that c* is isometrically isomorphic to l'. Are c* and c isometrically isomorphic?
Please see the attachment for better symbol representation.
