The discussion centers on the correct quantification of integers a, b, c, and d to indicate that they cannot be zero. The proposed notation, "∀ a, b, c, d ∈ ℤ - {0}", is deemed non-standard but effective for conveying the intended meaning. Participants agree that clarity for the reader is paramount, even if the notation isn't conventional. Alternative expressions, such as "{ a, b, c, d } ⊆ ℤ - { 0 }", are also suggested for precision. Overall, the focus is on ensuring that the representation accurately communicates the non-zero condition for the integers.

TL;DR Summary
I just have this random question and I was wondering if the following quantifier below is correct to represent/symbolize nonzero integers ## a, b, c, d ##:
## \forall a, b, c, d\in\mathbb{Z}_{\neq 0} ##
Does the above quantifier represent/symbolize that all of the integers ## a, b, c, d ## cannot be ## 0 ##? Is this correct?

It is non-standard, but all that really matters is that the reader understands what you mean. I think they will.
If you want to write it perfectly correctly you could write:
$$\forall a,b,c,d\in \mathbb Z - \{0\}$$

Or, perhaps ##\{ a, b, c, d \} \subset \mathbb{Z} - \{ 0 \}##

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...
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...
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...
