    Consider the linear map L_k\colon x\mapsto x_{2k}. Then Y=\bigcap_{k\geqslant 1}\ker L_k. To conclude, show that L_k is linear and bounded.

    Re: Question in the analysis

    Are you sure this course work is from a class you are taking? You seem to be saying that you do not know what any of this means. For example, do you know what " l^1" means? How is the topology defined on that set ("group" is, mathematically, the wrong word)? How is "closed" defined in that topology?
