Is there a package with LaTeX symbols for the poset relations "covers" and "is covered by", as seen in ? I've tried creating ⋅> and &lt;⋅ symbols on my own using \cdot, &lt;, and >, but the spacing between the two symbols tends to vary, as does the surrounding space, in ways that don't look good.

I know what my symbol or character looks like, but I don't know what the command is or which math alphabet it came from. How do I go about finding this out?

I use LaTeX to take quick notes about my programming work.  I have a couple of frustrations:    I need to use underscore a lot because of variables named with underscores.  However, I have to escape each one of them "\_", thus making my notes less readable on the markup side. I commonly want to use "&lt;" and "&gt;" symbols - why oh why are the default representations of these symbols "¿" and "¡"?   Is there anyway I can alter LaTeX so that "_", "&lt;", and ">" literally typeset as "_", "&lt;", and ">"?

I have this tex: \(\mu_{A}\left(x\right)\in \[0,1  \right\]\)  The issue here is that [ and ] are not showing around 0,1, why is that?  Thanks.

I did not know that latex had different symbol for opening and closing quotation marks. I've used it like "abc" every where and just realised that I really should have used ``abc". Is there anyway I can convert all the quotations to become like ``abc"? Doing it manually will take forever as I have a lot of quotations.

This is best explained by example. Suppose I have the following:  \[     \begin{align*}     C_3 \rightarrow 6 automorphisms\\     C_4 \rightarrow 8 automorphisms\\     C_5 \rightarrow 10 automorphisms     \end{align*} \]   How can I get the word "automorphisms" to display as if it were not enclosed by the brackets?

I was wondering what the proper LaTeX code would be to display something like this:    You don't have to include the mathematical symbols, what is important is the structure.

is incompatible with the enumerate and itemize environments. Is there a typographical reason not to wrap a list around a figure or is it a technical limitation of LaTeX? If it is a technical limitation, is there any work (new packages or changes to LaTeX) currently being done to eliminate the limitation in the future?  Edit: To respond to some of the comments: I realize that there are "gymnastics" which can make this work. I do not have an example of the problem. Whenever I run into a problem with wrapfig because it is near an enumerate or itemize environment, I search for an easy solution, find none, and move the figure elsewhere. In the vast majority of cases, the cost of learning the complex solutions isn't worth the benefit of keeping the figure where I want it.

I am trying to insert the symbol in the title of the question, which I copied from a PDF article, but it appears as space in the output file. What is the corresponding LaTeX command?

Is it possible to automatically "add" \left and \right commands in front of all brackets? The source code should be left intact, but LaTeX should interpret every pair of brackets as if they were preceded by such commands. This is because adding \left and \right commands is time consuming and makes source code longer and less readable. I considered defining new commands such as \lb and \rb for \left( and \right), but it doesn't seem very elegant to me: what if I also want to add square brackets for example?  Any ideas? Thanks.

How do I typeset annuity and life-insurance symbols, actuarial notation in ConTeXt. I see there are packages available but not for ConTeXt.    Thanks

Is there a way to typeset the symbol ":⇔" correctly in LaTeX (i.e. with the right alignment and spacing)?  I know that using :\Leftrightarrow or :\Longleftrightarrow gets me the symbol I'm looking for (more or less), but the spacing doesn't look right to me. Constructions using \iff or \colon didn't really seem to do the trick, either.   Do I have to define such a symbol myself (if so: how?), or is there a package proving this? Unfortunately, I did not find anything myself (especially because I don't know what to search for exactly; I got the description "defined to be logically equivalent" from Wikipedia, since I didn't even know the correct name).

When typing &lt; or &gt; in LaTeX and compiling with pdflatex, the less than and greater than symbols appear at upside down exclamation points. I'm not in math mode.

Below you can see an arrow with a plus and a minus sign on top of it. How is this achievable in latex? Further possibilities: arrow with only plus and arrow with only minus sign on top. How can I do this?

Does anybody know how to make the following symbol in LaTeX? I think it is some calligraphic \mathcal{E}.     It is not anywhere in  and online font recognizers do not recognize it.   The general font in the book I got this symbol from, Introduction to Quantum Optics by Grynberg, is not very extraordinary: this is a formula containing the strange symbol:

Does anybody know how I can get exactly that symbol for the set of real numbers in LaTeX?   Additional image:    In this picture you have the symbol for the set of integers, real numbers and complex numbers. I think this must be a package.
