Limit Superior and Limit Inferior

Limit Superior And Limit Inferior

In mathematics, the limit inferior (also called infimum limit, liminf, inferior limit, lower limit, or inner limit) and limit superior (also called supremum limit, limsup, superior limit, upper limit, or outer limit) of a sequence can be thought of as limiting (i.e., eventual and extreme) bounds on the sequence. The limit inferior and limit superior of a function can be thought of in a similar fashion (see limit of a function). The limit inferior and limit superior of a set are the infimum and supremum of the set's limit points, respectively. In general, when there are multiple objects around which a sequence, function, or set accumulates, the inferior and superior limits extract the smallest and largest of them; the type of object and the measure of size is context-dependent, but the notion of extreme limits is invariant.

Famous quotes containing the words limit, superior and/or inferior:

    Moreover, the universe as a whole is infinite, for whatever is limited has an outermost edge to limit it, and such an edge is defined by something beyond. Since the universe has no edge, it has no limit; and since it lacks a limit, it is infinite and unbounded. Moreover, the universe is infinite both in the number of its atoms and in the extent of its void.
    Epicurus (c. 341–271 B.C.)

    And what is an authentic madman? It is a man who preferred to become mad, in the socially accepted sense of the word, rather than forfeit a certain superior idea of human honor. So society has strangled in its asylums all those it wanted to get rid of or protect itself from, because they refused to become its accomplices in certain great nastinesses. For a madman is also a man whom society did not want to hear and whom it wanted to prevent from uttering certain intolerable truths.
    Antonin Artaud (1896–1948)

    If the only new thing we have to offer is an improved version of the past, then today can only be inferior to yesterday. Hypnotised by images of the past, we risk losing all capacity for creative change.
    Robert Hewison (b. 1943)
