Cauchy Net

In mathematics, a Cauchy net generalizes the notion of Cauchy sequence to nets defined on uniform spaces.

A net (xα) is a Cauchy net if for every entourage V there exists γ such that for all α, β ≥ γ, (xα, xβ) is a member of V. More generally, in a Cauchy space, a net (xα) is Cauchy if the filter generated by the net is a Cauchy filter.

Famous quotes containing the word net:

    Afraid lest he be caught up in a net of words, tripped up, bewildered and so defeated—thrown aside—a man hesitates to write down his innermost convictions.
    William Carlos Williams (1883–1963)
