Hi,

could anybody provide me links with some user-friendly beginner explanation
about limit cycle oscillators?

Thanks.

This should be funny? You could provide me an address via the group post or
you could "ask me" what is my address...

Wow... very original... Im impressed!!! Karamba!!!

Try to google about limit cycle oscillator, and please find some basic info
about it... Guess what? You will not find it!!!

And because of that i asked in this group for a help...

So you can try to help me, or "eat my Shorts" Helmut...

I am giving up... Thanks for nothing... Well, thanks for insults... Vielen
Dank, Helmut!

What a shame that this is the quality of discussion on this interesting
topic.
As I hunt I don't see introductory information.
Several of the most tempting links are not general access.
arxiv lists this term back to 1998:

http://search.arxiv.org:8081/?query=%22Limit+cycle+oscillator%22&qid=11665426649072br213.423nN-1628467276&byDate=1&startat=20

There are lots of biblio refs that you might reach back into from a
university library. Somewhere they have to trace out the initial use of
the term.

This looks pretty interesting. Don't get too lost. First principles
should be better presented and more accessible. You may be on a tendril
that is branching for the sake of branching e.g. a PhD pump. You seem
to have reached the edge of the internet.

Hey Wabnigger, you always like to present yourself an Arian
physics hot shot in the NGs. So, you surley can do much better
than just eating other posters shorts. For instance, as
I suggested to you 6 times before, start to atone and help the
Israeli Yehiel Porat to promote his theory. He knows it and he
is waiting. So, go help Yehiel. Continue with the thread that
I started for Yehiel with the post:
http://groups.google.com/group/sci.chem/msg/33082c606ed857a0
Now follow that example, Wabnigger. Do something for Yehi.
Help Yehiel, Helmut. Don't continue to be a feiger Schweinehund.

Look, Wabnigger, the ghosts from you fingering Jews to the Nazis
in the 1940's obviously still haunts you... and all your revisionism
attempts about Hitler's habits will not ameliorate that. It will help you
as little as your bragging that you personally have known Nazi Generals.

Why should I care for Yehiel? Who in hell ist he?
Explain that.

Yes, you just explained yourself in your 2-liner that are a Jew hater,
you Schweinehund! You've finally admitted it in your Freudian slip! .

Wabnigger read here about your Nazi background again, from the
days where the ghosts from you fingering Jews to the Nazis
in the 1940's obviously still haunt you... and all your revisionism


attempts about Hitler's habits will not ameliorate that. It will help you

.... ahahahaha... well the most festive characterization and

yeah, that is pretty closely related to Wabbies' manners, but it
is not a depiction of Wabnigger himself: Here is a more accurate
portrait
http://www.paul-gerlach.de/jogger+hund/pics/Schweinehund.jpg
http://www.rodeland.de/laufen/fotos/wm_v/schweinehund_4.jpg
and here is a woman who talks about him, the Schweinehund:
http://video.google.com/videoplay?docid=3155031239913132402&q=Schweinehund&hl=en
>
On the taxonomic level Schweinehund is also closely related to the
term Köter/Koeter which means, mutt or mut which Wabnigger also
portrays in a rather elegant way by his NG mannerisms. The word
Köter's, comes from Kot which means (dog)-shit, and hence a
Köter is a shit covered mutt, or mut, as so aptly seen in Wabbies
first name Helmut, where he is referring to himself as a fifthly street
dog, full of shit, .... ahahahahaha.... ahahahaha as is officiated in
http://www.dict.cc/?s=Koeter

But we are digressing here much to the relieve and delight
of Wabnigger, the verköterte Schweinehund. So, Wabbie
should rather be reminded that he ought to atone & help Yehiel
Porat, and not play even more stupid than he, Mutt, already
is and try to weasel out with "Who in hell ist Yehiel?"...
... when he, Helmutt, full well knows that Yehi is not in hell but
in Israel and that Yehi is posting even today her in s.p.
So much for Wabbies' incessant hate on Jews!
Here is the link again which has the request for Helmut
to atone and help Yehiel:

Not empty, but also not filled with BASIC informations about limit cycle

The BASICS is math. Start with fractals, bifurcation diagrams etc.
How far do you want to proceed, what is your application,
why don't you tell us more.

Fractals and bifurcation diagrams are used for much wider range of nonlinear
systems and they are not strictly bonded for limit cycle oscillations!
The math is not the basics! The math is used for the description of some
physical process.

Well, what kind of the process are limit cycle oscillations and how are they
mathematicaly described? A simple example would be nice...

Thanks on this link. It is a very good introduction. However, i am familiar
with the terms as attractors, bifurcations and similar. I am looking for the
mathematical/physical description of simple limit cycle oscilators, i.e. how
to define the limit cycle oscilator via mathematics/physics?
