So impressed was I by mAsterdam's japanese 'reference' symbols, I decided to add them to my list of useful unicode. Yes, I am indeed, that cool, and hereby post said list partly as a google-group test, and partly (perhaps) to assist in the more mathematical cdt discussions:

inequality : ≠
inference : →
implication : ⇒
not : ¬
and : ∧
or : ∨
xor : ⊕
xor : ⊻
exists : ∃
for all : ∀
membership : ∈
non-membership : ∉
equivalence : ⇔
empty set : ∅
subset : ⊂
proper subset : ⊆
superset : ⊃
proper superset : ⊇
union : ∪
intersection : ∩
cartesian product : ∏

division : ÷
naturals : ℕ
integers : ℤ

rationals : ℚ
reals : ℝ
complex: ℂ
infinity : ∞
