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.
AND ∧
OR ∨
XOR ⊻
XNOR ↔
NAND ↑
NOR ↓
NOT ¬
These are the only two that seem standard:
AND ∧
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.
