Discussion Overview

The discussion revolves around a proposed theorem related to a recursive function defined for positive integers. Participants explore the validity of the theorem and seek critiques or proofs, with connections made to physical concepts such as kinetic energy.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant presents a theorem involving a recursive function and a limit involving a summation, suggesting it may be a new contribution.
  • Another participant provides examples using Mathematica to test the theorem, indicating that no counterexamples have been found for specific values of a and b.
  • A different participant expresses uncertainty about the theorem's originality and acknowledges its potential truth based on their observations.
  • One participant admits to an error in their previous calculations but claims the theorem appears valid for values of a and b up to 10,000, while noting that this does not guarantee its universal truth.
  • A participant connects the theorem to a physical formula related to kinetic energy but suggests that this may not be the appropriate forum for such a discussion.

Areas of Agreement / Disagreement

The discussion remains unresolved, with multiple competing views on the theorem's validity and originality. Participants express varying degrees of confidence in the theorem without reaching a consensus.

Contextual Notes

Some limitations include the dependence on specific values of a and b, the lack of a formal proof, and the unresolved nature of the theorem's validity across all integers.

Can anyone prove the next theorem, if it's new I think it's mine.
Thank you for trying.

Definition

a en b are integers a>0, b>0

[tex]X1[/tex] f(1) =a
[tex]X2[/tex] f(n+1) = (2f(n))mod(a+b)

Theorem
[tex] \lim_{n\rightarrow\infty}\sum_{k=1}^{n}|{f(k+1)-f(k)}|\left(\frac{1}{4}\right)^k = \frac{ab}{2(a+b)}[/tex]
 
Physics news on Phys.org
In Mathematica I can give different values for a and b, like a=8, b=9 and this is not a counterexample. n must be a large number like n=50 or n=100. If there is a single counterexample then this is enough to prove the theorem is wrong.
 
Nice observation, I don't know if this is already known. Anyways it seems to be true:smile:

How did you come up with that?
 
HB - I erased my post very shortly after making it as I realized in my program I had the formulas all wrong. I now have it correctly entered and It appears to be true for all a and b up to 10k (not that that means it will always be true :wink:)
 
Pere, I came up with the theorem when I defined a physical formula about kinetic energy.
[tex]E(t)=\frac{m_1*m_2}{2(m_1+m_2)}V(t)^2[/tex]
I think this is not the right forum to start a discussion about this.
