The strange thing which this question is about is that removing the braces from the \defs (e.g. in \def\B{\mathbb B} removing those around \mathbb B, and similarly from all the other \def commands) seems to cause problems. For example, removing them all except those of \B and \C causes: ./mworks.sty:844: LaTeX Error: \mathbb allowed only in math mode. See LaTeX manual or LaTeX Companion for explanation. Type G

It's usually best to provide your code in the form of a [meta.tex.stackexchange.com/questions/228/… as it really helps those who might be able to provide assistance. Welcome! –cmhughes Oct 31 '12 at 16:24 Just to follow my previous comment- there's a danger that your question might get closed if it is not posed clearly; your question is very reasonable, but would benefit greatly from being turned into a Minimal Working Example –cmhughes Oct 31 '12 at 16:49 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote You need to be careful to use mathmode correctly; in particular, \mathbb needs to be in
#198 - 1 msg Messages sorted by: http://www.math.illinois.edu/~ajh/tex/course/intro2.html [ date ] [ thread ] [ subject ] [ author ] Dear TUG-support: I'm sorry to disturb you. I'm now writting the thesis. My advisor suggest me to math mode put one whole chapter as appendix. The problem with me is that if I put the chapter as normal one , it complies well, if I use the following commands: \appendix \chapter{my appendix} \input{chapte_nine} The following allowed only in error came out: ! LaTeX Error: \mathrm allowed only in math mode. I checked and found that .e.g. \textit{fully connected neural network}, if I don't use \textit, it works, if I use, then the above error comes out. SO what's the problem? Thank you for your time! Sincerely yours, S.yu __________________________________________________ Do You Yahoo!?

a display math mode, used for displayed math formulas. At any given point during the processing of a document, TeX is in one of those three modes. The behavior of TeX depends on the mode it's in. For example, certain characters (like the underline or caret symbols) are only allowed in a math mode, while others (like the "greater than" symbol) take on completely different meanings, depending on whether TeX is in text or in math mode. (Try this: write some ordinary text that includes the string ">From" (which is often generated by email software), and see what the ">" symbol becomes after compiling the document. In math mode, by contrast, ">" does what you'd expect: it serves as the "greater than" symbol.) Text mode. This is the normal, or default, mode of TeX. TeX stays in that mode unless it encounters a special instruction that causes it to switch to one of the math modes, and it returns to text mode following a corresponding instruction that indicates the end of math mode. Ordinary (inline) math mode. Mathematical material to be typeset inline must be surrounded by single dollar signs. For example: "$a^2 + b^2 = c^2$". The single dollar signs surrounding this expression cause TeX to enter and exit (ordinary) math mode. Display math mode. Material that is surrounded by a pair of escaped brackets ("\[" and "\]"), or by "equation environments" such as \begin{align} ... \end{align}, or \begin{equation} ... \end{equation} is being processed by TeX in "display math mode." This means that the expression enclosed gets displayed on a separate line (or several lines, in case of multiline equations). Longer mathematical formulas and numbered formulas are usually "displayed" in this manner. Note that the commands for entering and leaving display math mode are distinct (\begin{...} or \[ for entering and \end{...} or \]), in contrast to the ordinary math mode, where a single dollar sign serves both as entry and exit command. This allows for better error checking. (This is a major difference between LaTeX and AmSTeX or Plain TeX. In the latter two TeX versions, a double dollar sign ($$) is used to indicate the beginning and end of display math mode. While the double dollar sign (still) works in LaTeX, it is not part of the "official" LaTeX command set (in fact, most books on LaTeX don't even mention it) and its use is disc
