Hi, Josi,

We haven't forgotten you, glad to have you here in our board.

Why not join the word game or the rhyming one?

Where do you all come from and are you still attending school?! Im in my last year at school and hopefully I have my a-levels in three weeks. Just waiting to get my written results and than in 3 weeks I have got an oral exam in Music. After that I wanna go to University and study Hydrology. Right now I live in Berlin and I enjoy the life in the big city.

You probably know me from Matheboard, where I am a moderator. People say that I speak English quite well, but I for myself feel that I need more practice, which essentially is the reason why I am here. As I figured out that the best way for me to extend my active vocabulary and reduce my grammar errors is thinking thouroughly about individual sentences, I'm trying to help you by correcting your texts and explaining the mistakes you have made (don't feel addressed, if you don't need that help ). If you've expected to get something about me as a person and not about my motivation to be here, there you go: I'm currently a physics student at the University of Vienna (although I'm tinkering with the idea of starting to study mathematics parallely and see which suits me better) and am interested in computer science (besides physics and mathematics, of course), guitar music (that is, playing the guitar) and discussing interesting topics with my friends (drinking beer). Hope, I won't annoy you too much.

Differential equations is a field that I find particularly interesting and I wouldn't mind discussing it in English. Sturm-Liouville problems, however, are something I never heard of until now, so I guess my answer would be "no"...

I guess so, Sturm-Liouville problems seem to be somewhat similar to certain forms of the Schrödinger equation. (The correct term would simply have been "education", I think.)

I remember my old physics textbook containing a few pages that discussed how to solve the Schrödinger Equation (in time-invariant, onedimensional form) for the "particle in a box" problem, then concluding that minor changes to the potential function result in a problem that only can be solved by numerical means. It's good to know that there are important potential functions (I consider the harmonic potential to be quite important, when I think about single hydrogen atoms...) where the Schrödinger Equation still results in wave functions that can be described analytically.

This sounds really interesting; I have no idea how a set of differential equations can result in a series converging against a certain function, though. Could you enlarge on that a little? Is the Fourier Series a special case of series expansions resulting from Sturm-Liouville problems?

 ACH hat Folgendes geschrieben: Also, I am not sure what you mean by the correct term being education - please be aware that it's hard to tell sarcasm over the 'net.

I wasn't being sarcastic at all, my remark referred to the question mark you appended to the word "degree".

It's good to know that there are important potential functions (I consider the harmonic potential to be quite important, when I think about single hydrogen atoms...) where the Schrödinger Equation still results in wave functions that can be described analytically.

The SE can actually be solved analytically for an even more complex case (but I think it's the most complex you can get) which yields better results: that is the Morse potential Vm(x) = D ( 1- exp(-bx))^2 . Solving this one is really hard though afaik.

Could you enlarge on that a little? Is the Fourier Series a special case of series expansions resulting from Sturm-Liouville problems?

The basic idea is this: let f(x) be a function that satisfies the boundary conditions of the SL equation that we are talking about (e.g. y(a)=0=y(b)).

Then it can be shown that one can write f(x) as

are the eigenfunctions of the SL problem and their coefficients.

We can find the by using the orthogonality of the eigenfunctions:

- take eqn (1), multiply by & integrate:
(using bra-ket notation for simplicity)

but using orthogonality unless
therefore

Hence

If the eigenfunctions are normalized then
so .

Thus, in conclusion

(we can also get Green's function in a series form from this)

This eigenfunction expansion is the same as the Fourier series in the case of the SL problem i.e. where the eigenfunctions are trigonometric.

In all likelihood that wasn't too clear so you are probably better off having a look at the wikipedia article or in a textbook.

I hope you excuse my interference here, as I cannot contribute to your conversation (a poor 18-year-old secondary school student as I am is not yet able to understand it - but I will hopefully be able to understand it some years from now).

However I have two remarks:
1. This is rather "Off-Topic", so probably you would like me to split the topic? However, I would be the last to suppress such interesting conversations, so I believe the conversation should only be encouraged.

2. My second remark goes into this direction: Why not use to better visualize your ideas? Thomas was so nice to implement that into the board software some time last year.
You can use it like the Matheboard-Latex, so that
 Code: $\sum\limits_{k=0}^{n}\, \binom{n}{k}p^k(1-p)^{n-k}=1$

gives

 ACH hat Folgendes geschrieben: In all likelihood that wasn't too clear so you are probably better off having a look at the wikipedia article or in a textbook.

It was clear enough to give me a idea of what the series expansion is all about. The procedure seems to be quite similar to what I read in the Mathworld article about Generalized Fourier Series (to maintain honesty, I have to point out that it's two years now since I read that article).

Whereas the German Wikipedia article about Sturm-Liouville theory disappoints me (the English one seems to be better), I just discovered that the book about differential equations I recently ordered ("Differential Equations and Their Applications" by Martin Braun, you probably know it) has a chapter entitled "Sturm-Liouville boundary value problems". I hope I'll soon have more time, so I can get further into that matter.

 MI hat Folgendes geschrieben: This is rather "Off-Topic", so probably you would like me to split the topic?

As I don't want to raise philosophical discussions about whether or not you can get off-topic in the off-topic area of a forum, I remain indifferent.
