Topological LimitsIf . in an infinite collection of sets in ., the set . of all points . ∊. such that every open set about . meets all but a finite number of elements of . is called the . of . (i.e., Lim̄ . = .). The set . of all . ∊ . such that every open set about . meets infinitely many elements of . is called the . of ., (i.e., Lim̅ . = .).In-Situ 发表于 2025-3-25 07:37:55
