Unfortunately each turn becomes time by time more tricky. The problem is to find out a trick where the property of the Powers (non K dependence), under FLT equation fail. I've another trick here that use all what shown till now, but, i hope, will lead to a correct final answer. The problem is that it's soo long in computation that it's very hard to state, before start if I'm on the same ring... or I found the right exit... The start it's the same: A Power of an integer is squarable indipendently by $K$, with $11$ at condition $K|A$: So we can write ( remembering $x=X/K$ ): $\displaystyle A^2 = \sum_{1}^{A} 2X-1 = \sum_{1/K}^{A} 2x/K-1/K^2 = \lim_{K\to\infty} \sum_{1/K}^{A} 2x/K-1/K^2 = \int_{0}^{A} 2x dx= A^2$ If we can find, starting from $A^n=C^n-B^n$, an equation in A,B,C,K where we show the K dependence (with K under correct conditions) we have the proof of why Fermat is right. so another turn can be, starting from the same equation of the previous trick: $\displaystyle (A-1/K)^n =? (C-1/K)^n - B^n$ but turning it in Step Sum: $\displaystyle \sum_{1}^{A-1/K} 3x^2/K-3x/K^2+1/K^3 = \sum_{B+1/K}^{C-1/K} 3x^2/K-3x/K^2+1/K^3$ and subtracting term by term, as possible, the right hand from the left hand we arrive to a monstre equation K dependent in the form... $\displaystyle (A+B-C)^n = f(K)$ But before bore you with the long computation, the question is if someone can immediately see, before calculation that we will be, again, in a round trip (or in a yellow submarine) ? After long computation (to be cecked) the solution looks like: $(A+B-C)^3 =3B^2C^2/K-6CB^3/K-12ABC+3BA^2+6AB^2+6AC^2+9BC^2-3CA^2-9CB^2+3B^4/K+3B^3-3C^3-6ABC/K+3BC^2/K-3AB^2/K-3AC^2/K-3CB^2/K+3C^3/K-3B^3/K+3A^2/K+3B^2/K+3C^2/K+3BC^2/K^2-12CB^2/K^2+6AB/K-6AC/K-6BC/K+9B^3/K^2+6AC/K^2+12BC/K^2-6AB/K^2-6B^2/K^2-6C^2/K^2-6BC/K^3+9B^2/K^3+3C/K^3-3A/K^3-3B/K^3+3B/K^4$ Thanks ciao Stefano Last edited by complicatemodulus; June 16th, 2016 at 05:15 AM.

Still like a check on it... Thanks Ciao Stefano Last edited by complicatemodulus; June 21st, 2016 at 07:06 AM.

(this is the point, pls check...) But we will se we will arrive to an absurdum. The (2) In Step Sum: we left the equal sign, just remembering at the end K has to go infinity: $\displaystyle \sum_{1/K}^{A-1/K} 3x^2/K-3x/K^2+1/K^3 = \sum_{1/K}^{C-1/K} 3x^2/K-3x/K^2+1/K^3 - \sum_{1/K}^{B} 3x^2/K-3x/K^2+1/K^3$ or: $\displaystyle \sum_{1/K}^{A-1/K} 3x^2/K-3x/K^2+1/K^3 = \sum_{B+1/K}^{C-1/K} 3x^2/K-3x/K^2+1/K^3$ Lowering the right hand limits: $\displaystyle = \sum_{1/K}^{C-B-1/K} 3(x+B)^2/K-3(x+B)/K^2+1/K^3$ Solving the inthernal term and pulling out the known cube: $\displaystyle = \sum_{1/K}^{C-B-1/K} 3x^2/K-3x/K^2+1/K^3 + \sum_{1/K}^{C-B-1/K} 6Bx/K-3B/K^2 +3B^2/K$ $\displaystyle = \sum_{1/K}^{C-B-1/K} 3x^2/K-3x/K^2+1/K^3 + 3B(C-B-1/K)^2 +3B^2(C-B-1/K)/K$ Subtracting the cube from the left hand will rest: $\displaystyle \sum_{C-B}^{A-1/K} 3x^2/K-3x/K^2+1/K^3 =$ Again lowering the limits in the left hand: $\displaystyle \sum_{1/K}^{A+B-C} 3(x-B+C-1/K)^2/K-3(x-B+C-1/K)/K^2+1/K^3 =$ $\displaystyle \sum_{1/K}^{A+B-C}(6Cx/K-6BC/K-6Bx/K+3B^2/K+3C^2/K+3x^2/K+9B/K^2-9C/K^2-9x/K^2+7/K^3) =$ Again extracting the right cube: $\displaystyle \sum_{1/K}^{A+B-C}(3x^2/K-3x/K^2+1/K^3) + \sum_{1/K}^{A+B-C}(6Cx/K-6BC/K-6Bx/K+3B^2/K+3C^2/K+9B/K^2-9C/K^2-6x/K^2+6/K^3)=$ So we retun to: $\displaystyle (A+B-C)^3=$ $\displaystyle = - \sum_{1/K}^{A+B-C}(6Cx/K-6BC/K-6Bx/K+3B^2/K+3C^2/K+9B/K^2-9C/K^2-6x/K^2+6/K^3) + 3BC^2-6CB^2+3B^3+3CB^2/K-3B^3/K-6BC/K+6B^2/K-3B^2/K^2+3B/K^2$ ...second part will follow... Thanks ciao Stefano

That means if FLT equation has a result for n=3, than we found a new trinomial develope.... This seems an absurdum, so Fermat is Right. The main point now is: check, and check again if no bugs here... The same process can be made for any following $n$ and we are sure that the mixed product terms coming from the second degree (and following) terms will always create a non K dependent terms that will not vanish.

 June 24th, 2016, 02:35 AM #28 Banned Camp   Joined: Dec 2012 Posts: 1,028 Thanks: 24 Fore sure it's a booring think, but also my fault... I've no time (/friends/professors) to push a fully perfect version, so I left till now some bugs in the develope ...I'm trying to self check... I found 2 and in my last revision of this morning the end is: $\displaystyle (A+B-C)^3 = -12ABC+3BA^2+6AB^2+6AC^2+12BC^2-3CA^2-15CB^2+6B^3-3C^3$ So the "concept" for what FLT equation fails from $n>3$ seems right... but... Still waiting for a check on the concept, so if I'm aloud to make that algebra "reduction", than again push $K\to\infty$, or if this trick is wrong by concept... Thanks ciao Stefano

Nice, thanks, it means all the rest it's true...

Fermat Last Theorem... shorten as FLT in lot of place...

Thanks
