What does Cauchy mean?
Definition of Cauchy sequence : a sequence of elements in a metric space such that for any positive number no matter how small there exists a term in the sequence for which the distance between any two terms beyond this term is less than the arbitrarily small number.
Why are Cauchy sequences important?
A Cauchy sequence is a sequence whose terms become very close to each other as the sequence progresses. Cauchy sequences are useful because they give rise to the notion of a complete field, which is a field in which every Cauchy sequence converges. …
What is Cauchy sequence in real analysis?
A sequence is called a Cauchy sequence if the terms of the sequence eventually all become arbitrarily close to one another. That is, given ε > 0 there exists N such that if m, n > N then |am- an| < ε. Remarks. Note that this definition does not mention a limit and so can be checked from knowledge about the sequence.
