標題[其他] 不太懂 most finitely many 得意思
時間Sun Oct 16 14:18:31 2011
我在念Real Analysis的子數列的章節
If Xn is a bounded sequence of real numbers, then the following statements
for a real number x* are equivalent.
(A) x* = lim sup(Xn)
(B) If ε>0, there are at most finitely many terms of X that are greater
than x*+ε
請問這邊的 at most finitely many terms of X 意思是不是說 只要是有限的就可以
包含零個?

推 jacky7987 :只多有限個 可以沒有 10/16 14:28
→ jacky7987 :至多 10/16 14:28
→ ricestone :再怎麼多也只有有限個項,也不會到Countable 10/16 14:29
