AI Thread Summary
The discussion centers on the notation \(\frac{D}{p}\), which refers to the Legendre symbol in algebraic number theory, indicating whether a prime \(p\) divides the discriminant \(D\). Participants express confusion about the notation, clarifying that it does not imply \(D = p\). The Legendre symbol is crucial for understanding quadratic residues and non-residues. The conversation highlights the importance of notation in mathematical communication, particularly in advanced topics. Overall, the thread emphasizes the need for clarity in mathematical expressions.

I am given something of the following.

... there is an odd prime p with ( \frac{D}{p} ).

What exactly is that? No, it's not D = p. It's on page 5 if you want to look.

Thank you.

I remember writing it without a line... Jeez. I'm going crazy right now.
 

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 '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...
