Lemma 8.1.7. If ξ−1​(M)\xi^{-1}(M) has no maximum, then the construction above gives an isomorphism

Eξ∧𝒮M∙​(Z)Mf→∼Mf∧𝒮f⁡(M)∙​(Z′)Ef∘ξ,E_{\xi}\wedge_{{\mathcal{S}}^{\bullet}_{M}(Z)}M_{f}\mathrel{\mathop{\kern 0.0pt\to}\limits^{\sim}}M_{f}\wedge_{{\mathcal{S}}^{\bullet}_{f(M)}(Z^{\prime})}E_{f\circ\xi},

and ff provides a morphism of bimodule 22-representations Lf∘ξ∙→Lξ∙L^{\bullet}_{f\circ\xi}\to L^{\bullet}_{\xi}.
