Legendre equation , the Bessel equation and Sturm Liouville equation

Click For Summary

Discussion Overview

The discussion revolves around the Legendre equation and the Bessel equation, specifically regarding their classification as Sturm-Liouville equations and the orthogonality of their solutions. Participants seek to understand the proof of these properties and the necessary mathematical forms involved.

Discussion Character

  • Technical explanation, Homework-related, Conceptual clarification

Main Points Raised

  • One participant asks how to show that the Legendre and Bessel equations are Sturm-Liouville equations and seeks proof of the orthogonality of their solutions.
  • Another participant requests clarification on putting the equations into Sturm-Liouville form.
  • A participant provides a reference to the Sturm-Liouville form and mentions finding a mathematical explanation for the Bessel equation but expresses uncertainty about proving orthogonality.
  • One participant suggests that if the problem is stated correctly, the proof of orthogonality is well-known and can be found in mathematical methods literature.
  • A later reply indicates a realization of previously lacking information about Sturm-Liouville theory, suggesting a moment of clarity regarding the topic.

Areas of Agreement / Disagreement

Participants express varying levels of understanding regarding Sturm-Liouville equations and the orthogonality of solutions. There is no consensus on how to prove the orthogonality, and some participants indicate uncertainty about the necessary information.

Contextual Notes

Some participants acknowledge a lack of information about Sturm-Liouville theory, which may affect their ability to engage with the problem fully. The discussion includes references to mathematical forms and proofs that are not fully detailed in the thread.

Show that the Legendre equation as well as the Bessel equation for n=integer are Sturm Liouville equations and thus their solutions are orthogonal. How I can proove that ..?

Can you put it in sturm-liouville form?
 
Yes ...

see . this is the form of Sturm Liouville

i found the mathematical explain for bessel .

but i don't know how i can prove their solutions are orthogonal ..!


can you help me :confused:

Did you post the problem exactly? If so, as I interpret it, you do not need to prove that yourself. It is well known that the solutions to sturm-liouville problems are orthogonal and the proof can be found in any mathematical methods book.
 
yea

i understand that hour before .. i wasn't have enough information about sturm-liouville

or maybe my brain stopped :-p



thanks :)
