  1. What is the norm of a complex number? [duplicate]

    Jan 24, 2013 · 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 …

  2. Understanding L1 and L2 norms - Mathematics Stack Exchange

    Feb 6, 2021 · 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 …

  3. normed spaces - How are norms different from absolute values ...

    Hopefully without getting too complicated, how is a norm different from an absolute value? In context, I am trying to understand relative stability of an algorithim: Using the inequality $\\frac{|...

  4. What is the difference between the Frobenius norm and the 2 …

    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 …

  5. 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 …

  6. functional analysis - Sobolev space - norm $H^1$ and $H^1_0 ...

    Aug 16, 2013 · What norm are you using in $H^1$? or better saying what is the definition of $\|\cdot\|_ {H^1}$ for you?

  7. How do I find the norm of a matrix? - Mathematics Stack Exchange

    Feb 12, 2015 · I learned that the norm of a matrix is the square root of the maximum eigenvalue multiplied by the transpose of the matrix times the matrix. Can anybody explain to me in …

  8. matrices - Orthogonal matrix norm - Mathematics Stack Exchange

    Apr 22, 2016 · The original question was asking about a matrix H and a matrix A, so presumably we are talking about the operator norm. The selected answer doesn't parse with the definitions …

  9. 1 and 2 norm inequality - Mathematics Stack Exchange

    I know the definitions of the $1$ and $2$ norm, and, numerically the inequality seems obvious, although I don't know where to start rigorously. Thank you.
