Question 2. [2, 5, 4; 3 marks] (a) Consider the normed spaces (p,|| . ||p) where
1 < p <00. Prove that the canonical basis B := {en\n\
basis as follows:
1,...,} is a Schauder

(ii) Prove that

(iii) Prove that for loo, oo) that there is no Schauder basis.
(HINT: Use a counterexample.)
(b) Consider the normed spaces (co, ) of all sequences with limit equal 0.
Prove that the canonical basis 3:= {enn = 1,...,} is a Schauder basis for co.
