I am defining a new relation in one of my new papers. I want to use the following symbol, because it conveys the meaning of my relation. Is there such a symbol in LaTex ? It is very similar to \leq and \preceq. If not, is there a way to add new symbols by hacking the back-end of LaTeX.

  • Have you tried Detexify?

    Yes. I tried Detexify. No Luck. Apr 17 '13 at 21:59

    According to Every symbol defined by unicode-math, there is no such a symbol, although some are really close to what you have in mind.

    I'm now mildly curious about this relation. When you publish the paper, if you have put an electronic pre-print somewhere, please link to it here for us to read. Apr 18 '13 at 12:46

    I used this symbol in my paper arxiv.org/abs/1308.5170 Dec 21 '13 at 19:43

Here's an attempt (better than the first one).


\fbox{$A\xle B$}\fbox{$A \le C$}


enter image description here


You can draw it in TikZ and play with its shape:



                \draw [line width=0.06ex, line join=round, stealth'-stealth']
                    (1.5ex,0.67ex) -- (0, 0) -- (1.5ex, -0.67ex);
                \draw [line width=0.06ex, line cap=round]
                    (0.03ex, -1ex) -- (1.47ex, -1ex);


normal\newrel text, $math \newrel mode$

\Large Large\newrel text, $math \newrel mode$

    If you put the symbol in \mathrel (math mode), then you automatically get proper math spacing for a relational symbol. Apr 17 '13 at 22:35
  • @HeikoOberdiek, thank you for the comment. I've updated the code. Indeed, it's much simpler now. Apr 18 '13 at 5:38

Here is a start:

\newcommand\ltarreq{\mathrel{\raise 2pt\rlap{\rotatebox{20}{$\scriptstyle\rightarrow$}}%
    \raise 2.5pt\rlap{\rotatebox{-20}{$\scriptstyle\rightarrow$}}%
    \lower 2pt\hbox{$-$}}}

It's a bit ugly, but it shows you how to do what you want (almost).
