I read somewhere that this was proved sometime in the 80's, but that same source didn't mention that the proof was wrong. Of course I would cite the source but I can't find it again.. Does anyone know of any specific reason why this is still a conjecture?

I realize that for these sorts of measures there is often some pathological or special case getting in the way. Is that what is happening here?

Thanks :).

The MathWorld article fits your description (mentions that it was "proved" in the 1980's, but does not mention a flaw in the proof), but I'm not sure if that's what you were thinking of.

Thanks Ackbach! I'm not sure it's the same article.. but I should have checked at MathWorld anyway since there is a nice paper trail there :). Thanks again.
 
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...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
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...
