I discovered an inequality.. reverse schur

by pythag011, Dec 15, 2008, 11:39 PM

Instead of schur, we have

Prove that if a,b,c are positive reals, then $b(a - b)(a - c) + c(b - c)(b - a) + a(c - a)(c - b) \le 0.$

is \operatorname working? $\operatorname{SPAM} x.$ No it isn't. Oh well.

Is reverse schur equivalent to schur? Is it strong or weak?

Hmm...

Should I try to bash all geometry problems using complex numbers?

Oh well...

Can this be generalized? (Reverse schur).

Interesting...

post some of the geometry problems you are doing?

hmm

your ineqality doesn't seem to be very happy for $a = b$ ...

like if $a = b = 1$ and $c = 2$ then it becomes $1\le 0$ which is wrong

HOPEFULLY I AM NOT MISREADING STUFF

bad physics. Relearn. Now.

I already did.

With the new quote-simulation program (read my post on james4l's blog) I can slow my computer so much time goes backwards!

Just enter it for a thread with 1 trillion posts.

Time will flow baackwards.

Only 19.99! A 5000000 dollar value!

You can go backwards in time

Unfortunately, you'll have to stay there, because you can't go forward.

Nope it's 227 now. I should create some kind of anti-F5 button, so I can DROP a blog's views

1. By Perelman's proof, the Pionxare Conjecture is corect
2. No. The task of solving these problems has been proven to be NP, but not be P.
3. Apply an absolute zero Fourier Transform. Then, the velocity of every particle is 0. By the Fourier Untransforming Thereom, the velocity is f(R^3), where f is the Busy Beaver function (Zeb)
4. Yes. Consider the nth derivative of f(pi^e), where f is the busy beaver function. It must be an integer if pi^e is rational. But, it is positive and less than 1. Therefore, pi^e is irrational. Using the transcendality-irrationality bridge thereom, pi^e is transcendental.
5. This is a direct consequence of Zeb's conjecture.

How did you get into my blog?
