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 ∃limxn. And if k0⊆l∞, with sequence {xn}∈k0, then k0=limn→∞xn=0.
The help would be appreciated!
