AI Thread Summary
The discussion centers on the applicability of Schur's Theorem to fractions within the context of Ramsey Theory. The researcher has established several bounds related to Schur and Ramsey numbers and noted that an arithmetic sequence of fractions does not conform to Schur's Theorem, although they are uncertain about the correctness of their proof. They express interest in fractional Ramsey theory, suggesting a potential link to Schur's Theorem and seek guidance on how to proceed. Additionally, there is a request for feedback on their proof from others in the forum. The conversation highlights the intersection of combinatorial concepts and ongoing research challenges.

Hi all, I am currently doing research in Ramsey Theory and my research question is: does Schur's Theorem apply to fractions? Right now I am up to the point where I have proven several basic bounds of Schur and Ramsey numbers and have proven that an arithmetic sequence of fractions does not obey Schur's Theorem(I'm actually not sure whether my proof is correct, so I will post it up if anybody would like to check it for me).

Anyway, I searched online and found out that there is something called fractional ramsey theory and it led me to hypothesize that Schur's Theorem actually does apply to fractions(since Ramsey Theory and Schur's Theorem are related) but I'm not too sure where to start : can anybody help me? Thank you!

My skill in combinatorics is not so great that I could offer a good critique of your proof, but I would be very interested in seeing it.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
