Not known Factual Statements About upper and lower limits

In mathematics, the Restrict inferior and Restrict outstanding of a sequence could be regarded as limiting (that's, eventual and Excessive) bounds within the sequence. They can be thought of in a similar manner for any functionality (see Restrict of a perform). For a established, They're the infimum and supremum with the established's limit points, respectively. Normally, when you will discover numerous objects about which a sequence, operate, or established accumulates, the inferior and superior limits extract the smallest and largest of these; the sort of object plus the measure of dimension is context-dependent, though the notion of maximum limits is invariant.
