    Convergence Relation
Click For Summary

Discussion Overview

The discussion centers on the relationship between convergence and asymptotic behavior in the context of ordinary differential equations (ODEs) and partial differential equations (PDEs). Participants explore whether convergence of solutions implies an asymptotic relation, particularly when using methods like Adomian decomposition.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • One participant questions if convergence of a solution necessarily implies an asymptotic relationship, seeking clarification on potential exceptions.
  • Another participant suggests that convergence indicates a limit that the function cannot exceed, which they interpret as indicative of an asymptote.
  • A later reply elaborates on the context of the question, specifically relating to the analytical solutions of ODEs and PDEs, and inquires if convergence through methods like Adomian decomposition equates to asymptotic behavior.

Areas of Agreement / Disagreement

Participants express differing views on whether convergence implies asymptotic relations, with no consensus reached on the matter. Some participants agree with the notion that convergence suggests an asymptotic limit, while others raise questions about exceptions and the relationship between different solution methods.

Contextual Notes

Participants have not fully defined the terms "convergence" and "asymptotic" in this context, and the discussion lacks resolution on the conditions under which convergence might not imply asymptotic behavior.

hello,
does convergence imply asymptotic relation of an ordinary differential equation?
 
Physics news on Phys.org


sounds right.
 


kindly expound ...are there cases where a convergent solution might not be asymptotic?
regards
 


well are you talking about the convergence of f(x) as x goes from 0 to infinity?

If it converges, that means that there is a value that f(x) cannot exceed. That sounds like an asymptote to me.

I am by no means an expert in this kind of thing, your statement just seemed right to me.

someone else may be able to help you more thoroughly.

Hi,
well let me put the question a bit clear...my concern area is on ode and pde...my question is when you solve a pde/ode analytically and get a solution by asymptotic means does this imply that if solution exists then if using convergence of the pde/ode as an alternative method for solving the same...read adomian decomposition...does it mean convergence amounts to asymptotic and vice versa?
