How they can be typed in Emacs?

`C-x 8 RET'  (command `ucs-insert')

i wrote a mode for this
〈Emacs Unicode Math Symbols Input Mode (xmsi-mode)〉
http://ergoemacs.org/emacs/xmsi-math-symbols-input.html

though i ask for donation. (it's not difficult to find on the net,
however)

but in any case, you can easily define keys in emacs in so many ways.
See

agda2-mode comes with a very convenient latex input mode that lets you insert
symbols as you would in latex (e.g. \rightarrow - or abbreviated \r).

If you don't want to install Agda (which is understandable) I think that this
file will work:
http://code.haskell.org/Agda/src/data/emacs-mode/agda-input.el .

I use the `TeX' input method (C-x RET C-\ TeX RET) to input basic math
symbols. Some examples: \exists ∃, \forall ∀, \in ∈, \notin ∉, \int ∫,
\infty ∞, \to → and so on. It even does basic superscript and subscripts
like this: (a + b)² = a² + b² + 2̣̣ab, H₂O.

Hope this helps.

Alternatively, you can map those characters with xmodmap directly on
your keyboard. http://paste.lisp.org/display/123256

   ∀α,∃β, α∈[0,2] ∧ β∈[3,5] ⇒ α³ ≤ β²
