Homotopy classification of $S^{2 k - 1}$ -bundles over $S^{2 k}$

Zhongjian Zhu, Jianzhong Pan

In this paper, we classify the homotopy types of the total spaces of $S^{2 k - 1}$ -bundles (or fibrations) over $S^{2 k}$ for $2 \leq k \leq 6$ . One of the two key new ingredients in the…

Complexes equivalent to $S^{2 k - 1}$ -fibrations over $S^{2 k}$

Zhongjian Zhu, Jianzhong Pan

In this paper, necessary and sufficient conditions are obtained for the attaching map $f$ of the top cell of a CW complex to have the homotopy type of the total space of $S^{2 k - 1}$ …
