Q59·Section II (Mathematics)·59 of 180Topology — the upper-limit topologyLet τ\tauτ be the topology generated by {(a,b]:a<b}\{(a,b]:a<b\}{(a,b]:a<b} on R\mathbb{R}R, an=1na_n=\frac1nan=n1 and bn=−1nb_n=-\frac1nbn=−n1. Then: OptionsA(an)(a_n)(an) and (bn)(b_n)(bn) converge in τ\tauτB(an)(a_n)(an) converges and (bn)(b_n)(bn) does not converge in τ\tauτC(an)(a_n)(an) does not converge and (bn)(b_n)(bn) converges in τ\tauτDneither (an)(a_n)(an) nor (bn)(b_n)(bn) converges in τ\tauτPick an option to check your answer.Show answerShow solution Report a problem with this question← Q58All questionsQ60 →Keyboard: A–D answer · S solution · ←/→ previous/next
