Does any normed space X can be embedded into another normed space Y, such that X is density in the Y and dim(Y)=dim(X)+1.

    What does $\dim Y=\dim X+1$ mean if $X$ (and $Y$) is infinitely dimensional?2012-10-09

    Perhaps it is better write codimension(Y)=1 ?2012-10-09

    Yes, codim(Y)=1!2012-10-12
