and we have to have a second subject besides maths.
Now, for some bad Idea, I chose Computer Schience
ANd now I get into an argument about whatever they talk about. They spread wrong ideas, proofs and stuff all over the place. I have that one course I have to take and the "teacher" is a doctor of science (!) who works at uni for 15 years
I prove her wrong every single lesson and she would NEVER EVER believe me
but if you want to know if $1/x$ can be expressed as a Dirichlet series, I would recommend spending a couple of hours trying before posting on main - and explain how far you got
@OldJohn I know a sum or product of 2 dirichlet series is also a dirichlet series ... otherwise Im quite clueless apart from your statement about x ...
I also know a derivative a dirichlet is a dirichlet ...
Let f(x),g(x) > x for all real x and let f(f(x)) = g(x). g(x) is given. What are the conditions on g(x) such that there is a unique solution f(x) , such that the arc length between f(a) and f(b) is minimum for all a and b ??
Hmm no - idea about that - even without the arc condition, you are talking about a fractional iteration, I believe, and they get pretty darned difficult.
There have been some interesting questions along those lines on MO
Let P : C 2 → C be a polynomial in two variables x, y. Show that if P is a linear map then P(x, y) = αx + βy + γ for some α, β, γ ∈ C. Express α, β, γ in terms of P
let p: c^2 -> c be a polynomial in two variables x,y. show that if p is a linear map then p(x,y) = $\alpha$x + $\beta$y + $\gamma$ for some alpha,beta,gamma in C. express alpha,beta,gamma in terms of P
so i got the whole first part, i showed what needed to be shown
but i'm not sure how to express alpha,beta,gamma in terms of P
Oh: evidently Zounds is supposed to be God's Wounds as in the nails of the cross, hence rhymes with wounds. I do know lots of powerful people, it is just that most do not reply to my email, so it is a hollow sort of honor. Or, from a book by Ernest Bramah:
One humble friend in the same village is worth two influential uncles in the palace of the Emperor.
In England there is an existing slang usage or "birds" for "girls," used for at least decades. Not in the US. no real reason for it either way, slang just happens.
There seems to be a mechanism where people can assign a star to a comment in chat. I have two new ones, the Emperor thing and the bird item. I even got a badge at one point, X comments in chat with at least Y stars each. The badge was called Outspoken I think. Although Entertaining Or At Least Trying To Be would have hit closer to the mark.
@OldJohn, I think it would work if only yhe badges better reflected the full experience of the site. So, for example, if they had an Asshole badge as a bronze, then a silver version and a gold version for the honest to god assfuck, that would be informative.
The odd thing is that I wound up emailing a guy with fairly serious asperger's, over some MO stuff that sometimes appears on MSE. It was pretty nice. So my feeling is that the compulsion to post useless crap is a condition distinct from autism or asperger's.
John is referring to my "white noise machine" which has been very helpful. @Jonas, I don't know. I just think in terms of one being an inability to fully process incoming information, as in social cues or criticism, and the compulsion being to spray stuff outwards, consistent with exhibitionism except that maybe the people watching do not really matter.
@JonasTeuwen, right, and not necessarily in your control, although you must know that there is some societal penalty for seeming too peculiar. How is the manuscript coming?
