Treffgeraden und NullinvarianzWie gliedert sich der dreidimensionale projektive Raum durch die sich treffenden oder meidenden Geraden? Der Autor demonstriert, wie man aus dieser Frage zu einer berraschend einheitlichen Beschreibung von Regelscharen, Kongruenzen und Komplexen kommt und wie man die harmonische Lage und die Plckerschen Geradenkoordinaten direkt ber die Treffrelation erhalten kann. von Hans J. Stoss

I really wanted to love these, and I *almost* did. They are comfortable and cute. But they are a little wide across the mid-foot so they were a little sloppy on my feet. The platform is quite high, and while at 5'3" I appreciated the extra height, between that and being too wide, I felt they were an accident waiting to happen. If they were slightly more narrow and a little lower, I would have been in love, but I had to return them. They seem true to size except for the extra width.
