In 1958, I. M. James defined octonionic Stiefel spaces V_k(O^n)—the space of orthonormal k-frames in O^n with natural topology and raised two fundamental questions about V_k(O^n): (1) Is the projection π:V_k(O^n) → V_q(O^n)(q < k) a fiber map ? (2) Is V_k(O^n) a manifold ? We gave partial answers to both of them. This talk is based on joint works with Professor Zizhou Tang and Professor Chao Qian.
