Let the space k be all convergent sequences of real numbers. Let the space k0 be the space of all sequences which converge to zero with l∞ norm. Are lp∩k and lp∩k0 complete in || ||∞? Are they complete in lp norms?
If k⊆l∞, with sequence {xn}∈k, then ∃lim. And if k_{0} \subseteq l_{\infty}, with sequence \{x_{n}\} \in k_{0}, then k_{0} = \displaystyle\lim_{n \to \infty}x_{n} = 0.
The help would be appreciated!
