Abstract

Our objective here is to describe cellular structures of \(\mathbb{F}_k (M)\) naturally associated with the bases of \(H^* (\mathbb{F}_k (M))\) for M = ℝ n+1, S n+1 of Theorem 4.2 and §6 of Chapter V. The basic ideas are the following: first, that the twisted product representation \(\mathbb{F}_k (\mathbb{R}^{n + 1} ) \simeq \,\mathbb{R}_1^{n + 1} \propto \cdots \propto \mathbb{R}_{k - 1}^{n + 1} \) introduced in Chapter II, §4 leads to a twisted product
$$ H_* (\mathbb{R}_1^{n + 1} ) \otimes \cdots \otimes H_* (\mathbb{R}_{k - 1}^{n + 1} ) \cong H_* (\mathbb{F}_k (\mathbb{R}^{n + 1} );\mathbb{Z}) $$
on homology, which we write as
$$ \alpha _{r_1 s_1 } \otimes \cdots \otimes \alpha _{r_p s_p } \mapsto \omega = \alpha _{r_1 s_1 } \, \propto \cdots \propto \alpha _{r_p s_p } r_i < r_{i + 1} $$
for all 1 ≤ p ≤ (k - 1); and, second, that each p-fold twisted product ω leads to an imbedding
$$ \varphi _\omega \,:\,S_1^n \, \times \cdots \times \,S_p^n \, \to \,\mathbb{F}_k (\mathbb{R}^{n + 1} ) $$
of a certain kind. These maps provide us with the cells and attaching maps of the desired complex.
