Denote by G(k,n) the Grassmannian of linear subspaces of dimension k in Pn. We show that if n >m then every morphism \varphi:G(k,n) \to G(l,m) is constant.

Denote by G(k,n) the Grassmannian of linear subspaces of dimension k in Pn. We show that if n >m then every morphism \varphi:G(k,n) \to G(l,m) is constant.File in questo prodotto:
