| Popis: | Let V 5 be the del Pezzo 3-fold defined by the 6-dimensional linear section of the Grassmannian variety Gr ( 2 , 5 ) under the Plucker embedding. In this paper, we present an explicit birational relation of compactifications of degree-two rational curves (i.e. conics) in V 5 . By a product, we obtain the virtual Poincare polynomial of compactified moduli spaces. |
