WebThis show that liminf n→∞ a n ≥ M and since M is arbitrary it follows that ∞ ≤ liminf n→∞ a n ≤ limsup n→∞ a n. The proof for the case A = −∞ is analogous to the A = ∞ case. Proposition 1.6 (Tonelli’s theorem for sums). If {a kn} ∞ k,n=1 is any se-quence of non-negative numbers, then X∞ k =1 X∞ n=1 a kn= X∞ n ... WebFinitely but not countably additive set function. Let X be any countable! set and and let F be the cofinite set, i.e., A ∈ F if A or A c is finite (this is an algebra). Then show that the set function μ: F → [ 0, ∞) defined as μ ( A) = 0 if A is finite μ ( A) = 1 if A c is finite is finitely additive. I have started the argument by ...
