- notation - What does := mean? - Mathematics Stack Exchange
It's one common notation for stating that the left-hand side is defined as (in contrast to equal to) the expression on the right-hand side
- notation - Symbol for “such that” (not in set) - Mathematics Stack Exchange
A better, but less common, notation is $\varepsilon$ (formatted with $\varepsilon$) You can find answers and comments related to that latter symbol $\varepsilon$ in the linked posts
- Meaning of the notation $ [G - Mathematics Stack Exchange
3 What does the notation $ [G : H]$ mean in group theory? Does it mean the same as quotient group? I have seen the above notation a lot while studying group theory but it still remains unclear to me about the meaning of this notation?
- notation - What is the mathematical symbol for range? - Mathematics . . .
An unsophisticated question from a neophyte: Given the numbers: $1,2,3,4,5$ What is the symbol for the range of the numbers? i e the lowest-highest number in the set For example, the min max
- Notation for the least common multiple and greatest common divisor
The (bad) notation $ (a,b)$ is often used for the greatest common divisor; somebody uses $ [a,b]$ for the lowest common multiple Why are they bad, in particular the former? Because $ (a,b)$ is already used for several other purposes
- Function Map notation? - Mathematics Stack Exchange
Interestingly, it did mention the notation I'm asking about in the context of domain and codomain (vs range, which is the terminology used in all the mathematics courses I've taken at my college)
- notation - Name of a vector of 1s? - Mathematics Stack Exchange
Your notation $\mathbf {1}$ (or $\mathbf {1}^T$ if you insist that $\mathbf {1}$ is a column vector) is fine and is commonly used Just define it when you are using it
- Why is abuse of notation tolerated? - Mathematics Stack Exchange
In mathematics, abuse of notation occurs when an author uses a mathematical notation in a way that is not formally correct but that seems likely to simplify the exposition or suggest the correct intuition (while being unlikely to introduce errors or cause confusion)
