[Tex/LaTex] the LaTeX code for an “open semicolon”

symbols

May I know what is the LaTeX code for the following symbol? I can't find it in detexify.

Best Answer

According to Shapecatcher, this is a "Z notation relational composition". Looks like you can get it in the objectz package:

\documentclass{article}
\usepackage{oz}
\begin{document}

$\fcmp$

\end{document}

[Tex/LaTex] Symbol: Center of Mass (dowelpin)

I don't think it's available as a proper symbol, but you could use TikZ to draw it. By using the units em or ex, the symbol will scale corresponding to the surrounding text.

dowel pin / center of mass / BMW symbol

\documentclass{article}

\usepackage{tikz}

\newcommand\centerofmass{%
    \tikz[radius=0.4em] {%
        \fill (0,0) -- ++(0.4em,0) arc [start angle=0,end angle=90] -- ++(0,-0.8em) arc [start angle=270, end angle=180];%
        \draw (0,0) circle;%
    }%
}

\Huge It scales! \centerofmass

[Tex/LaTex] What command to use for reversed $\vDash$

Constructed symbol

If the font does not provide the symbol, the mirroring can be done with package graphicx:

\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}

\makeatletter
\providecommand*{\Dashv}{%
  \mathrel{%
    \mathpalette\@Dashv\vDash
  }%
}
\newcommand*{\@Dashv}[2]{%
  \reflectbox{$\m@th#1#2$}%
}
\makeatother

\begin{document}
\[ A \vDash B \Dashv C \]
\end{document}

Remark:

The stuff with \mathpalette ensures that the symbol is properly scaled if it is used in different contexts (as index, in fractions, …).

Font package `MnSymbol`

If package MnSymbol is loaded (it also changes other math symbols), then the symbol is available as \leftmodels:

\documentclass{article}
\usepackage{MnSymbol}
\begin{document}
\[ A \leftmodels B \]
\end{document}

Font package `mathabx`

If package mathabx is used (also changes other math symbols), then the symbol is called \Dashv:

\documentclass{article}
\usepackage{mathabx}
\begin{document}
\[ A \Dashv B \]
\end{document}
