Let z i j 's be the coordinates of P N, by definition we can state that Σ m, n, the image of σ m, n in P N, is Serge Marc Cantat (born 3 June 1973, in Paris) is a French mathematician, specializing in geometry and dynamical systems.

Building on this, we give effective methods to compute intersection products in projective … WebSegre classes of vector bundles, cones, and subschemes. Let V Pn be any subvariety. The degree of V may be expressed as the intersection number of V with a general linear subspace of complementary dimension: (2.1) degV = Z Pn Hn dimV V; where H= c 1(O(1)) is the hyperplane class in Pnand, as recalled above, R Pn
WebSecant varieties of Segre and Veronese varieties (and more generally Segre-Veronese vari-eties, which are embeddings of a product of projective spaces via the complete linear system of an ample line bundle) are very classical objects that go back to the Italian school of math-ematics in the 19-th century. WebSegre variety, and we de ne the product using this map, that is we are aiming for: Proposition 6.2. Let XˆPmand Y ˆPn. Then the image of X Y under the Segre map is the product (in the sense of category theory) of Xand Y. Lemma 6.3. The Segre Variety V is the product, in the sense of cat-egory theory, of Pm Pn. Proof.
