errata

Hi,

someone pointet out some error in one of the solutions for exercise 1, (in the powerset construction, one state was not marked as accepting, where it should), I repaired that and replaced the solution. And I am always thankful for feedback on spotted errors and unclarities.

Sometimes, there are typos in the slides, which I see only during the lecture. I repair also those, without especially announcing it here.

Anyway, at the end of the semester, the slide set and "script" will be uploaded again in an updated version (without announcing all improvements here).
