Nontrivial linear projections of the Grassmannian Gr_3(C^6)
Yanhe Huang, George Petroulakis, Frank Sottile +1
A typical linear projection of the Grassmannian in its Plucker embedding is injective, unless its image is a projective space. A notable exception are self-adjoint linear projectio…

Injectivity of generalized Wronski maps
Yanhe Huang, Frank Sottile, Igor Zelenko
We study linear projections on Pluecker space whose restriction to the Grassmannian is a non-trivial branched cover. When an automorphism of the Grassmannian preserves the fibers,…
