comment How can I typeset those braces?
@egreg Yep, you're right. Unfortunately, SE only lets you edit comments once, so my error belongs to the ages now ;)

comment How can I typeset those braces?
@egreg it depends on if the OP is doing this inline or in an equation (or some other displaymath-type environment), and what's going on inside the brackets, etc.

comment How can I typeset those braces?
@researcher The best answer should probably also mention Knuth notes that squiggly brackets should have some small spacing, \bigl\{\,..., ...\,\bigr\}. Also, using \bigl\{ and \bigr\} works great...for inline or display stuff. For footnotes, I think you should use \left\{...\right\}.

Heh, I'm working on Java while answering a TeX question, I mean $\displaystyle\bigl\{O^{(i)}, e^{(i)}\bigr\}^{M}_{i=1}$

comment Problems with beyond the margin of a article?
I think you might want to try producing parts of the map independently before assembling them altogether. I suspect you have too many linebreaks (these guys `\`)...

comment Turn marginpar into a regular paragraph
@jon For sure! But I was just throwing ideas out there for the OP to consider :)

comment Turn marginpar into a regular paragraph
"Back in the Day" (i.e., the 1700s), they used to flow around margin notes. See, e.g., Teddy Roosevelt's Winning of the West for examples...

It looks like \mathop{\tt and}\nolimits in plain TeX...

Also, consider using \langle instead of <, and \rangle instead of > for Bra-Ket notation...

comment How to type sheaf hom
Although, note, the H is in Hartshorne a mathscript letter, so one should use \mathscr{H} and one of the many fine mathscr packages

comment Prose Statement of Formulas
(Also, fwiw, it may be easier to use \begin{pmatrix}...\end{pmatrix} instead of \bigll(...\bigrr), since it will autosize it for you!)

comment Prose Statement of Formulas
I've seen \mbox{} used instead of \text{} for this job, could you explain the merits of \text{} over \mbox{}?

comment What's the proper way to typeset a differential operator?
Springer-Verlag's monograph style had \def\D{\mathrm{d}} for the differential operator. I agree with Hendrik Vogt's post below for spacing, that one should typically (but not always) write \,\D x. The exception: after a fraction, e.g., \frac{\sin(x)}{x}\D x is OK; and after a function, e.g., \cos(x)\D x is also OK. But I think there is no single golden rule...it's an art, not a science.

comment Permutation cycle notation
For math spacing, you could try \; which is not quite as much as a quad (and \, for finer spacing).

comment Proposition command doesnt work
And if you want the text to be upright, not italicized, you can always add \theoremstyle{definition}\newtheorem{rant}{Angry Rant}. More examples may be found in the AMSthm documentation.

comment How do I make ``` appear as ' + “ and not ”+ '?
In the TeXbook, Knuth suggests writing '\thinspace'', for '+''.

comment Graphing sine function in MetaPost
+1 for answering the question, using metapost (not Tikz), and not using fancy LaTeX dialects (i.e., you avoided LuaLaTeX).

comment Correct way to typset esssup (essential supremum)
Note that \, and friends are math spacing whereas \thinspace and co. are text spacing, which is a critical distinction (it produces errors otherwise).

comment How should imaginary numbers be typeset?
Unrelated suggestion: define \def\I{i} and simply use \I everywhere in your math. You can fix your one macro later, after finishing your manuscript. After many similar problems, I found this helps me maintain productivity.
