1. How to test a multivariable function have PDE?

2. If it have, How to guess a multivariable function's possible PDE?
Which algebraic methods can solve these kind of problem?Wink

If I wouldnt have you registered with my own hands I would think you are a bot.
Are you?

No i am not a bot.
Just i do not have question to ask for a long time. Now i have, so i come.

But your question is quite general, and what does it have to do with tetration?

Undecided I have one function that i want to know how to make it and want to know where it come from. i find that tetration is a math forum, so i ask here.

Well, originally its about tetration and associated topics.
But maybe if you are more specific we can see what we can do anyway.

Not me. I find this appearence simply rude. Why can't people respect if some others want to make them a forum about a certain topic? And want have a certain concentration, athmosphere, familiarity and mathematical level with this?

For me: this thread is spam (we had also another one recently).

what PDE is satisfied by cheta(2x + log(x))^(zeta(y^y + sqrt(7))) ?

yes , this is a parody.

although i am intrested in PDE , have talked about PDE ( with or without relating tetation ) and im willing to learn about PDE ... this question it seems is too general and it seems we need to do all the *work* for 0 purpose and unrelated to tetration.

further there is a lot already written about PDE , so most concrete questions are answered in books or online pdf ( free access is another matter ofcourse , but not my responsibility ).

if the OP (original poster) or someone else can justify the OP (original post) or give a more specific question or give a meaningfull answer to my parody question , i might withdraw my words(*) and give it a try.

( * im not apologizing in any way , my reaction seems logical )

i do not wish to insult the OP , (s)he is free to post another thread if (s)he wishes.

However, this is specifically for tetration.

You could go somewhere else, though. Try sci.math (use Google groups if you have no other way), try something like mathforum.org, or pages like that. Just googling "math forums" gives a number of pages you could try.

@Gottfried & Tommy: To me it seems like an honest request, just misguided insofar as where he's posting it goes. I don't think calling it "spam" and making fun of it helps here, and just seems too hostile.
