In this article we obtain a complete description of the congruences of lines in P^4 of order one provided that the fundamental surface F is non-reduced (and possibly reducible) at one of its generic points, and their classification under the hypothesis that (F)_red is smooth.

Abstract
In this article we obtain a complete description of the congruences of lines in P^4 of order one provided that the fundamental surface F is non-reduced (and possibly reducible) at one of its generic points, and their classification under the hypothesis that (F)_red is smooth.File in questo prodotto:
