Speaking of the vectors in
the Dirac notation, they are typically written as |x
> for x being some label for the state (eg. it could be an
eigenvalue of an operator which acts on it).
If you're planning to write these vectors in HTML, I find the best way to do so is like this:
|x<big><big>></big></big>
for the state I have written above. It seems ironic that a hypertext language developed at
CERN should have such difficulty with these kinds of expressions!
