# Math Help - Whats that maths font?

1. ## Whats that maths font?

Hi, I'm looking for a font that is commonly used in mathematics, similar to blackboard font (\mathbb{}) for special number sets. Problem is, I don't know what it is called, and can't say specifically what it's used for, I just remember seeing it somewhere. I think the context was families of sets, such as the powerset, but I'm sure I've sen it used for other things too.

Anyway, there can't be that many common fonts used for maths, so can someone give some examples using LaTeX?

Thanks

Some examples:

$x \in \mathbb{R}$

$\mathcal{L}\left\{ {f\left( t \right)} \right\} \equiv F\left( s \right) = \int_0^\infty {{e^{ - st}}f\left( t \right)dt}$

$\mathfrak{h} \subseteq \mathfrak{g}$

All of these symbols are available in the MathType fonts, available by free download from the Design Science website: MathType: Font Installers

Fonts used:
$\mathbb{R}$ (Euclid Math Two)
$\mathcal{L}$ (Euclid Math One)
$\mathfrak{h}$ (Euclid Fraktur)
There's also a font in the MathType font set that looks like the TeX font Computer Modern. This one is called Euclid, and is useful if you have to work in Word (to collaborate with colleagues using Word, etc.) but want your documents to look like TeX.

if you're still interested in this subject, have a look at this document: A Survey of Free Math Fonts for TeX and LaTeX by Stephen G. Hartke.

Here's a demonstration of various blackboard fonts: blackboard.ps. For representation of number sets I'm preferring the doublestroke font package.
