Math & Science ⇒ Calligraphic Symbols with Subscripts

[andreasam]

I'm trying to get curly letters using \mathcal
e.g. \mathcal{F}
this works perfectly well but If I am trying to add a subscript to F, i am getting a > as the subscript.

I've tried both \mathcal{F}_i and \mathcal{f_i}

Any help would be most welcomed, thank you

Hi,

$\mathcal{F}_i$ works well for me. The unexpected > appears only with $\mathcal{F_i}$.

I hear you that it is working for you but it is not working for me at all.
Could there be another reason why mine is not working?

I'm using MikTex 2.9.

And these are not working:-

Code: Select all

$\mathcal{F}_i$
$\mathcal{F}_{ni} $
$\mathcal{L} \subseteq \mathcal{F}_a $

Along with a few more very similar

Could there be another reason why mine is not working?

Yes, of course. It could be a package in your document preamble which is not compatible, or your math font. You could post your preamble here. The best would be if you would post a complete small document which shows the problem. The we can test that to find the cause, and we don't need to guess.

Hi Stephan,

I have uploaded the file with this post.

There actually are no packages used in the file as I am building my final documents in sections. So currently it is a plain tex file.

Thanks for your help so far.

In that case you could fix it by adding curly braces around \mathcal{...}, before the subscript

Code: Select all

\documentstyle[11pt]{article}
\begin{document}
 $ L ={\mathcal{F}}_i$ 
\end{document}

Thank you.

Another solution is to change documentstyle to documentclass
