WebOct 14, 2024 · The Grassmannian manifold refers to the -dimensional space formed by all -dimensional subspaces embedded into a -dimensional real (or complex) Euclidean space. Let’s take the same example as in [2]. Think of embedding (mapping) lines that pass through the origin in into the 3-dimensional Euclidean space.

I've proved that it is a $2$-covering of the classical grassmaniann and I think it should represent its orientation cover (because I read that it is orientable), …
