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? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 98.112.57.143

再怎麼多也只有有限個項,也不會到Countable
