fundamental sequence; Cauchy sequence
Mathematics term for a sequence where terms become arbitrarily close to each other as the sequence progresses. Synonymous with コーシー列 (Cauchy sequence).
See also: コーシー列 (コーシーれつ)
The completeness of the real numbers is equivalent to every fundamental sequence converging.
Compound of 基本 (fundamental) and 列 (sequence). The term is a direct translation of the English 'fundamental sequence', an older name for Cauchy sequences.
