    Notation
AI Thread Summary
The notation \(\nabla \prod\) is questioned for its clarity and context, as it combines two symbols that appear confusing. The discussion suggests that if it were \(\nabla \times\), it would represent the curl operator, but \(\nabla \prod\) is interpreted as the gradient of the product of sequences. Participants encourage providing context or relevant documentation to clarify its meaning. The mention of "Pi" implies a connection to multiplication, indicating that further explanation is needed for proper understanding. Overall, the notation requires additional context to be fully comprehended.

\nabla\prod
can anyone can explain this notation to me?
 
Mathematics news on Phys.org
That's just two symbols which don't make any sense like that.
Can you explain in which context you found them and/or maybe provide a copy of the relevant part of the document (like a scan or copying the sentence)?
 
If it were \nabla\times, then it would be the "curl" operator.
 
It's the gradient of the PI vector. lol.
 

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

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...

Thread 'Non-orthogonal bases'

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'

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...
