- 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
- 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
- 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
- normed spaces - The difference between $L_1$ and $L_2$ norm . . .
The $1$-norm and $2$-norm are both quite intuitive The $2$-norm is the usual notion of straight-line distance, or distance ‘as the crow flies’: it’s the length of a straight line segment joining the two points
- normed spaces - Simple explanation of uniform norm sup-norm . . .
I've read the Uniform Norm Wikipedia page, but my most of it went over my head What is the sup-norm in simple and or intuitive terms? Are there any good examples which illustrate it?
- linear algebra - Understanding of the theorem that all norms are . . .
This proof is really a way of saying that the topology induced by a norm on a finite-dimensional vector space is the same as the topology defined by open half-spaces; in particular, all norms define the same topology and all norms are equivalent There are other ways to prove that using the Hahn-Banach theorem
- functional analysis - Sobolev space - norm $H^1$ and $H^1_0 . . .
What norm are you using in $H^1$? or better saying what is the definition of $\|\cdot\|_ {H^1}$ for you?
- 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
