What Wikipedia says

In mathematics, the limit inferior and limit superior (or limes inferior and limes superior) of a sequence can be thought of as limiting (that is, eventual and extreme) bounds on the sequence. They can be thought of in a similar fashion for a function (see limit of a function).
