WebSep 5, 2024 · Definition. If such a p exists, we call {xm} a convergent sequence in (S, ρ)); otherwise, a divergent one. The notation is. xm → p, or lim xm = p, or lim m → ∞xm = p. Since "all but finitely many" (as in Definition 2) implies "infinitely many" (as in Definition 1 ), any limit is also a cluster point.
