- 2-norm vs operator norm - Mathematics Stack Exchange
The operator norm is a matrix operator norm associated with a vector norm It is defined as $||A||_ {\text {OP}} = \text {sup}_ {x \neq 0} \frac {|A x|_n} {|x|}$ and different for each vector norm In case of the Euclidian norm $|x|_2$ the operator norm is equivalent to the 2-matrix norm (the maximum singular value, as you already stated) So every vector norm has an associated operator norm
- What is the norm of a complex number? [duplicate]
In number theory, the "norm" is the determinant of this matrix In that sense, unlike in analysis, the norm can be thought of as an area rather than a length, because the determinant can be interpreted as an area (or volume in higher dimensions ) However, the area volume interpretation only gets you so far
- Understanding L1 and L2 norms - Mathematics Stack Exchange
I am not a mathematics student but somehow have to know about L1 and L2 norms I am looking for some appropriate sources to learn these things and know they work and what are their differences I am
- Why is that the matrix $1$-norm and $\infty$-norm are equal to the . . .
However, this post seems to shatter my assumption: 2-norm vs operator norm Upon further examination, it seems that the operator norm and matrix norm only coincide (=) for the matrix $1$ -norm or the matrix $\infty$ -norm (and extremely limited cases for matrix $2$ -norm) Why is this so?

- Zero power zero and $L^0$ norm - Mathematics Stack Exchange
This definition of the "0-norm" isn't very useful because (1) it doesn't satisfy the properties of a norm and (2) $0^ {0}$ is conventionally defined to be 1
- What is the difference between the Frobenius norm and the 2-norm of a . . .
For example, in matlab, norm (A,2) gives you induced 2-norm, which they simply call the 2-norm So in that sense, the answer to your question is that the (induced) matrix 2-norm is $\le$ than Frobenius norm, and the two are only equal when all of the matrix's eigenvalues have equal magnitude
