\mathbb{R}, Q,C,F,N,Z, etc..
>>Do you use \mathcal? Example?
dont evne know what this does
>>Do you use \mathfrak? Example?
usually only for \mathfrak{a} (ideals)

>mathbb
Yes, in all the usual places. i.e. number fields, finite fields, ring of integers, affine space, etc.
>mathcal
Yes. In a ton of places.
>mathfrak
Yes. My most common use would be for ideals.
All of my papers depend heavily on the wasysym package. Damnit, Grothendieck-San.
mathbb: The usual sets. Also affine and projective spaces.
mathcal: Sheaves. Sometimes for sets/expressions too, just to make them look fancy.
mathfrak: Ideals.

idk what latex is

Theoretical physics
>Do you use \mathbb? Example?
Yes. All the generic stuff I use quite often, and [math]\mathbb{H}[/math] for the halfplane manifold.
>Do you use \mathcal? Example?
Yes. [math]\mathcal{A}[/math] for gauge connections and [math]\mathcal{F}[/math] for gauge curvatures.
>Do you use \mathfrak? Example?
Yes. [math]\mathfrak{I}[/math] for tensor quantities.

Physics
>Do you use \mathbb? Example?
Usually not. I used to, but now I think it looks ugly and use \mathbf instead for N, Z, R, C etc.
>Do you use \mathcal? Example?
Yeah, usually Hamiltonians and Lagrangians, or the path integral differential.
>Do you use \mathfrak? Example?
Usually not. I think I used to write the sum of states as a fractal Z or something, but that was some time ago.

mathbb{Z} for the integers
LaTeX is trash when you have to type up homework with it for a semester.

Math
>Do you use \mathbb? Example?
Yes. Kind of a stupid question, since it's everywhere.
>Do you use \mathcal? Example?
Yeah, I might use something like [math]\mathcal O_X[/math] for a structure sheaf or [math]\mathcal O_k[/math] for the ring of integers of a number field.
>Do you use \mathfrak? Example?
Yes. All ideals in commutative algebra should be written in mathfrak, like [math]\mathfrak p[/math].
>Field
Molecular biology.
>all those examples
nope
I mostly use \emph{}, \texttt{}, and \textbf{}

hm, I took an intro algebra course and D&F never used \mathfrak. Doing a intro to alg geometry course with "ideals, varieties, and algorithms" next though, maybe I will use it then
