On special rational curves in Grassmannians

摘要

Numerical and geometric characterizations, among all morphisms ${mathbb{P}^{1} rightarrow mathbb{G}(d, 2d)}$ , of those which are ${{rm GL}_{2d}(mathbb{C})}$ -equivalent to the canonical morphism induced by the Morita equivalence ${mathbb{C}^{d} otimes_{mathbb{C}}}$ –, are presented.
