\usepackage{mathrsfs} $\mathscr{F}$ Take a look at What are all the font styles I can use in math mode?

REVISED to add important note at end: Based on my answer at Big tilde in math mode, I adapted similar approaches for a wide hat and bar. After showing them in various math styles, I show composites of them, including the function of interest to you. \documentclass{article} \usepackage{scalerel}[2014/03/10] \usepackage{stackengine} ...

Never seen it either. However, here is a way of doing things: put everything into an array, with hhline to have a clean connection of vertical and horizontal lines. I define a normal and a bold version I don'tknow how to declare it, so as to have only one command for both versions): \documentclass[a4paper,12pt]{article} \usepackage{mathtools} ...

An implementation with tikz, shamefully adapted from this answer \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{calc} \newcommand{\house}[1]{% \tikz[baseline]{\node[anchor=base,inner sep=0.3ex](mynode){\ensuremath{#1}}; \draw(mynode.south west)--(mynode.north west)--(mynode.north east)--(mynode.south east); \path[use as bounding ...

\newcommand{\house}[1]{ \setbox0=\hbox{$#1$} \rule{.4pt}{\dimexpr\ht0 + 1.6pt} \overline{\mkern+1mu #1 \mkern+1mu} \rule{.4pt}{\dimexpr\ht0 + 1.6pt} }

Here is a plain TeX solution. The downside is, that \everymath is executed inside the "house". If you want every house to have the same height and depth, add a strut or a phantom inside it. \nopagenumbers% for cropping \def\house#1{{% \setbox0=\hbox{$#1$} \vrule height \dimexpr\ht0+1.4pt width .4pt depth \dp0\relax \vrule height ...

I copied the definition of \hbar, but inserted \delta instead of h and adjusted kerning. \nopagenumbers% for cropping \def\deltabar{{\mathchar '26\mkern -10mu\delta}} $\delta$ $\hbar$ $\deltabar$ \bye

Probably you are meaning \dh (U+00F0 LATIN SMALL LETTER ETH)? This is available in encoding T1: \documentclass{beamer} \usepackage[T1]{fontenc} \begin{document} \begin{frame} \dh \end{frame} \end{document}

CW from comments A good source for this correspondence is the file puenc.def in the oberdiek bundle; it consists of about 2000 lines like \DeclareTextCommand{\}{PU}[1]{#1\83\000}% U+0300 \DeclareTextCommand{\'}{PU}[1]{#1\83\001}% U+0301 \DeclareTextCommand{\^}{PU}[1]{#1\83\002}% U+0302 \DeclareTextCommand{\~}{PU}[1]{#1\83\003}% U+0303 ...

Harish Kumar's solution fails with babel 3.9j which is what TeX Live currently seems to have. MiKTeX is apparently using an older version (3.8m) which does not produce errors. [At least, this is my current working hypothesis - that the difference in versions of babel explains why my addition to the preamble is necessary with current TeX Live but not MiKTeX.] ...

In order to draw your symbol, follow the code below. \documentclass[12pt,letterpaper]{article} \usepackage{marvosym} \begin{document} \Cross \end{document} This symbol only works in text mode. An important resource that you might want to check out is Detexify. It allows you to draw different symbols, and the program compiles the list of symbols ...

I suggest you load the mathtools package and define a new macro, say \norm, as follows: \DeclarePairedDelimiter{\norm}{\lVert}{\rVert} While doing so incurs (slight) setup cost, it has several important advantages: Your code will become more readable (and easier to debug...) because you'll be writing things like \norm{(a,b,c)}^2, which focuses attention ...

for example: Q(\theta):= \Big\|(a,b,c) \Big\|^2 There is \big, \bigg, \Big, and \Bigg

Spaces in math mode are ignored and replaced with the appropriate surrounding space required for each component (like a relational or binary operator, or atom). So, you should be fine with 4 \pi G \rho \delta although technically 4\pi G\rho\delta would suffice.

The difference can be seen at the end of line. A space is breakable and a ~ is an un-breakable space. \documentclass[a4paper]{article} \usepackage[english]{babel} \usepackage[utf8]{inputenc} \usepackage{amsmath} \usepackage{graphicx} \usepackage[colorinlistoftodos]{todonotes} \title{Your Paper} \author{You} \date{\today} \begin{document} \maketitle ...
