comment Why use Konjunktiv I in mathematics?
I always thought it was to "define" what the function is. For example, in your sentence you define "ψ_n(x)" to be "Eigenfunktionen eines Hamiltonoperators Ĥ.", which they were not until you said so, so you cannot use "sind". springerlink.com/content/k1775207563q041g Not sure on that so I left it as a comment.
comment What could A, F and L mean in a course timetable?
Some pages (like badminton) have an explanation, while others (like basketball) just omit it. So it is not your fault ;)
