What is the proof that the limit of a Cauchy sequence of integers is an integer?

Click For Summary

Discussion Overview

The discussion centers around the proof that the limit of a Cauchy sequence of integers is itself an integer. Participants explore the properties of Cauchy sequences, particularly in the context of sequences composed of integers.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant requests a proof that the limit of a Cauchy sequence of integers is an integer.
  • Another participant suggests considering the necessary conditions for a sequence of integers to be a Cauchy sequence before presenting further work.
  • A participant asserts that a Cauchy sequence of integers is eventually constant and questions whether this constant term is the limit.
  • Another reply encourages demonstrating that a Cauchy sequence of integers is eventually constant, implying that this will clarify the limit's nature.

Areas of Agreement / Disagreement

Participants appear to agree on the notion that a Cauchy sequence of integers is eventually constant, but the implications regarding the limit remain under discussion without a consensus.

Contextual Notes

The discussion does not resolve the mathematical steps required to establish the proof, and assumptions regarding the properties of Cauchy sequences are not fully articulated.

prove that limit of a cuachy sequence of integers is an integer
 
Physics news on Phys.org
First think about what would have to be true for a sequence of integers to be a Cauchy sequence - then do some work and present it here.
 
a sequence of integers which is cauchy is eventually constant. is the constant term the limit?
 
Try to show "a sequence of integers which is cauchy is eventually constant" and the answer for the limit will become apparent.
