I disagree. If you'd put, say,

\chi_{\mathcal{E}} \chi_E y_{\mathcal{E}} y_E X_{\mathcal{E}} X_E

all on the same line you'd see that all of those subscripted letters sit on the same line.
If anything, your problem stems from putting a capital letter into the subscript to a lowercase letter that ...

Well, if you wish to discuss your problem here, you should present it here. A link to join your project won't do, IMHO.

You could try before your \documentclass line.
If that doesn't help, please provide a minimal working example that demonstrates your problem and a link to the class file you're using.

Hi there,
\rightarrow requires math mode, so if your pdfLaTeX isn''t stopping at errors, the first use of \rightarrow switches output to math mode---and in math mode, there aren't many language-specific characters defined (except for math, of course).
Either enclose all those \rightarrow commands by ...

Hi Bob,

I can't help but wonder...why do you define labels in this manner at all?
It doesn't look like you're referencing any of them---or if you do, the real question should have been ``why do my \ref{whatever} all point to the last use of \label{whatever} ?'' or so.
Besides, it would take quite ...

Well, \parsep has no effect, because it's used as vertical skip between paragraphs within an item of a list environment, such as enumerate or itemize.
\parindent would be a horizontal, not vertical skip at the beginning of a new paragraph.
\abovedisplayskip / \belowdisplayskip are only inserted ...

Well, I don't really see a difference using lmodern or not. Your

\newcommand{\wh}{\widehat}

just creates a shorter name `\wh' for `\widehat', you can see that \wh uses \widhat internally. Unless either is changed later, \wh and \widehat should produce exactly the same.
On the other hand, if you ...

Assuming you're using biblatex like the OP: did you run biber? Perhaps show your .blg file...

Here's an idea:

\documentclass{article}
\newlength\hwhatcwidth% half wide hat's contents width
\newlength\hwhatuwidth% half wide hat's contents width with contents upright
\newcommand*\halfwidehat[1]{%
\settowidth\hwhatcwidth{\ensuremath{#1}}%
\settowidth\hwhatuwidth{\ensuremath{\mathrm{#1 ...
