Special orthogonal, special unitary, and symplectic groups as products of Grassmannians

Lek-Heng Lim, Xiang Lu, Ke Ye

We describe a curious structure of the special orthogonal, special unitary, and symplectic groups that has not been observed, namely, they can be expressed as matrix products of th…

Minimal equivariant embeddings of the Grassmannian and flag manifold

Lek-Heng Lim, Ke Ye

We show that the flag manifold , with Grassmannian the special case , has an -equivariant e…
