abstract = "Ultralimits provide a very general way to pass to a limit. This procedure works for any sequence of metric spaces, its result reminds limit in the sense of Gromov–Hausdorff, but has some strange features; for example, the limit of a constant sequence of spaces Xn= X is not X in general (see 6.13(b)).",
