There are slide chain maps which are invertible up to homotopy. The inverses are given by the chain maps
Proof.
The proof is given by an explicit calculation. As an example (the remaining cases are checked analogously) we show that \(\mathrm{slide}^{-1}_{\mathbf{1}_1,B_1}\circ\; \mathrm{slide}_{\mathbf{1}_1,B_1}\) is homotopic to the identity by computing their difference and exhibiting an explicit null-homotopy: ◻
