Math & Science ⇒ Nonstandard Analysis in Latex

[dmj]

Hi Folks,

is there some convenient way to write nonstandard analysis terms such as *r.

At the Moment I use the tensor package, but this seems extremely improvised and cumbersome to me.

Here an example: \tensor*[^{\textup{*}}]{\mathbb{R}}{}

Has somebody a better idea?

Thanks.

Hi,

what about using simply the standard superscript command?

Code: Select all

\documentclass{book}
\usepackage{amsmath}
\usepackage{amssymb}

\begin{document}

$\sp{\ast}r$

$\sp{*}r$

$\sp{\ast}\mathbb{R}$

$\sp{*}\mathbb{R}$

\end{document}

Hi,

this seems like a better idea. This would also make something like

Code: Select all

$\sp{\ast}V(\sp{\ast}X)$

work.

Code: Select all

$\tensor*[^{{\ast}}]{V(\tensor*[^{{\ast}}]{X}{}}{})$

yields V(*X) instead of *V(*X).

I must say, I havn't seen any documentation about the \sp command so far. I am pretty new to Latex, though.

Thanks for the input so far. If somebody has an even better idea, please let me know

Sorry for the bump, but I had to do a gazillion of the *'s in my article (Nonstandard Analysis from a Model-Theoretic Perspective) and probably the best way to do so is:

Code: Select all

\usepackage{leftidx}

...

{^*}R, 

(and if you want, the package also works for left subscripts) {^*_1}R
