Abstract
The characteristic rank of a vector bundle ξ over a finite connected CW-complex X is by definition the largest integer \({k, 0 \leq k \leq \mathrm{dim}(X)}\) , such that every cohomology class \({x \in H^{j}(X;\mathbb{Z}_2), 0 \leq j \leq k}\) , is a polynomial in the Stiefel–Whitney classes w i (ξ). In this note we compute the characteristic rank of vector bundles over the Stiefel manifold \({V_k(\mathbb{F}^n), \mathbb{F} = \mathbb{R}, \mathbb{C}, \mathbb{H}}\) .
