[edit] Welcome

Hello, and a warm welcome to the Wikipedia. I have been reading up a bit on bifurcation theory lately, and need to learn more, so it was a very pleasant surprise to see somebody knowledgeable working on these articles. You seem to be doing pretty well, but if there is anything unclear, please do not hesitate to ask me on User talk:Jitse Niesen. Another good place to ask, if your question is related to maths, is Wikipedia talk:WikiProject Mathematics. In case you haven't found it yet, Wikipedia:WikiProject Mathematics and pages listed there give some hints specific to mathematical articles. In particular, I'd like to point out Wikipedia:WikiProject Mathematics/Participants, to show that you're not alone here; perhaps you want to add your name there?

Please remember to add references to the articles. For terms like homoclinic bifurcation, which are probably pretty much in every book on bifurcation theory, you can just list your favourite book if you do not know anything better.

I hope to see more contributions from you. Enjoy the place!

Cheers,

Dear Claire (hoping that I guessed correctly),

If your request at Wikipedia talk:WikiProject Mathematics/Graphics still stands, I'm happy to help, though I should warn you that the time I can spend on Wikipedia matters varies greatly depending on demands from my real job. Let me know what you had in mind.

I already changed one of your images (I replaced Image:heteroclinic.svg by Image:Heteroclinic orbit in pendulum phaseportrait.png at heteroclinic orbit) before I noticed your request. I hope that you agree that this change is an improvement.

Hi Jitse,

Thanks for your offer of help. I really want to update the bifurcation diagram page as at the moment it's useless. To start, some bifurcation diagrams of the 3 simple 1D bifurcations would be really helpful (saddle-node, transcritical and pitchfork). I've drawn what the saddle-node one would look like http://en.wikipedia.org/wiki/Image:Sn_dig.png here but it would need some axes etc. The dashed line represents unstable solutions, the solid line stable solutions. I guess it would be helpful for me to know how much you know about bifurcation theory before I give you far too much information about these that you already know.

Your heteroclinic orbit is much better than mine! Thanks!

I know a bit bifurcation theory, especially on the applied side. To give you an idea, I read Kuznetsov's "Elements of Applied Bifurcation Theory", though I skipped quite a lot and, of course, reading once through a book doesn't give one a proper understanding of the theory. Anyway, I know what the bifurcations you mention look like and I'll give it a try. -- Jitse Niesen (talk) 07:50, 29 July 2006 (UTC)

[edit] Welcome to the Mathematics project

Hi Claire. I saw you added your name to Wikipedia's Mathematics project participants list. Let me extend a warm welcome to the mathematics project. I see that Jitse has already pointed you to the relevant project pages, so I will just tell you that, if you have any questions or need any help, you are welcome to ask me on my user talk page: User Talk:Paul August. Both Jitse and I are admins so we can also help with any Wikipedia admin issues you might have. Thanks for joining the project, and again welcome. Paul August ☎ 18:58, 29 July 2006 (UTC)

[edit] Koch curve

Hi, by f I mean the height of the curve, as a function of distance along the base. It's not single-valued, which makes what I've said a little ambiguous....
