There are these logic gates symbols, but I am looking for the more low-level math-like symbols such as those found here, but for all the logic operations. There doesn't seem to be a central place for them, but these seem close.

I would like to know if from your perspective those are the standard symbols, or if there are others.

OR ∨

These are the only two that seem standard:

OR ∨

I'm not sure about the other ones, if there is a preferred set of symbols, or ones that are used most often in papers and the like.

  • $\begingroup$ They are all standard, and easily invoked in $\LaTeX$. $\endgroup$ – David G. Stork Jan 11 at 6:19
  • $\begingroup$ The table for gates isn't entirely correct, it is quite common to make, for example, a Nor gate by putting circles on the inputs of an And gate, that is in fact the whole point of the symbolic notation. $\endgroup$ – DanielV Jan 11 at 13:07
  • $\begingroup$ Yes, these are relatively standard; you may also see $\barwedge$ and $\overline{\vee}$ for NAND and NOR, and $\oplus$ and $\overline{\oplus}$ for XOR and XNOR. $\endgroup$ – Deusovi Jan 11 at 17:59
  • $\begingroup$ The de facto standard for papers is to use $\LaTeX$ (often together with packages like $\mathtt{amssymb}$). If you use $\LaTeX$, you don't need to know about Unicode. MathML defines a standard for mathematical content on the Web and includes definitions of a standard set of XML entities for mathematics and associated Unicode code points. MathJax which is used to enter and render mathematics on MSE uses MathML (and the $\LaTeX$ interface supports a useful subset of the MathML entities). $\endgroup$ – Rob Arthan Jan 14 at 16:34
