Very well executed and performed! Let me add my congratulations to the chorus. I assume that the thesis is in German, but I'm hoping that the core mathematical arguments at least are also available in English. Joe Gwinn PS: When I saw the posting subject, my heart froze - it sounded like an obituary notice - did Attila suffer a bad accident? The I read the text.
