Differentiable families of subspaces
A differentiable family of \(k\)-dimensional subspaces of \(K^ n\) is viewed as a mapping from the space of parameters \(M\) into the Grassmann manifold \(\text{Gr}_{k,n}\). There are given two local characterizations of such families and their globalized versions when \(M\) is contractible.
