# LaTeX syntax for karp reduction

What is the LaTeX syntax for Karp reduction (i.e. the lesser than sign with curved lines instead of straight lines)?

Please see this: tex.stackexchange.com/questions/14/how-to-look-up-a-math-symbol and I think you're looking for `\succ` or `\prec` and their friends: `\succeq,\preceq` –  Seamus Aug 8 '11 at 10:34
@Seamus: Thanks. Could u post this as an answer so that this gets an answer? –  user1876 Aug 8 '11 at 10:38
Purely for making it easy for people to find that canonical symbol-lookup question, I'm voting to close as a duplicate. –  Loop Space Aug 8 '11 at 11:05

In future, there are a number of ways to look up a symbol.

The "bendy inequality" symbols are:

`\succ`, `\prec`, `\succeq` and `\preceq`.

If you like the `eq` variants to bend too, then (with the help of the `amssymb` package you can:

``````\$\succ \prec \succeq \preceq \succcurlyeq \preccurlyeq\$
``````

Aesthetically, you may also prefer (as I do) the symbols `\succcurlyeq` and `\preccurlyeq` to their "non-curly" equivalents. –  Niel de Beaudrap Aug 8 '11 at 10:48
@Niels thanks for that! I couldn't remember what the command for them was. –  Seamus Aug 8 '11 at 10:56
Me neither, so I DeTeXified it. ;-) –  Niel de Beaudrap Aug 8 '11 at 10:58
@Seamus: Thanks. I have used DeTexify in the past but I completely forgot about it. DeTexify goes into my bookmark tab now. –  user1876 Aug 8 '11 at 11:15

`\propto` is Karp Reduction in LaTeX.
