Discuterò una costruzione geometrica, fatta insieme a De Concini, di una modificazione di una configurazione di sottospazi che trasforma i sottospazi in un divisore a incroci normali. Inoltre nel caso di iperpiani questa costruzione è legata alla generalizzazione della equazione di Kniznik-Zamolodchikov ed alla teoria dei nodi, per i sistemi di radici produce dei modelli particolarmente interessati.
I shall discuss a geometric construction, done with De Concini, of a blowup of a configuration of subspaces making it into a divisor with normal crossings. For hyperplanes this is related to a generalization of the Khiznik-Zamolodchikov equation and to knot theory. For root systems this produces a particularly interesting model.
