Unicode Cheatsheet for Greek & Math

I often find it useful to add some mathematical or greek symbols in my scientific computing Python programs (mainly in commentary). Here is a selection I've taken from Gnome Character Map for math. Greek was mainly generated by a Python script...

Math

Arithmetic
plus-minus _ ±
multiplication _ ×
division _ ÷
power _  ² ³
root _ √ ∛
infinity _ ∞
Operators
integrals and sum _ ∫ ∬ ∑
partial diff.             _ ∂
increment/Laplace _ ∆ (different from Greek delta : Δ)
nabla                      _ ∇
expectation             _ ⟨⟩ [apparently the double-struck E symbol kills Worpress...]

Relationships

  • equality            = ≈ ≠ ≡
  • inequality          < > ≤ ≥ ⩽ ⩾
  • proportional to     ∝
  • element of          ∈ ∉
  • subset of           ⊂ ⊄
  • quantifiers         ∀ ∃ ∄

Sets

  • integers            ℕ ℤ
  • real numbers        ℝ
  • complex numbers     ℂ
  • empty set           ∅

Arrows

  • arrows : → ⟶ ⇒
  • maps to : ↦ ⟼

Greek

pairs of lower case and upper case letters (putting a dot on letters which have very similar latin counterparts)

φ Φ (and also ϕ at U+03d5)
χ .
ψ Ψ
ω Ω

This greek table was first generated by these three lines of Python:
